5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Thank you for the opportunity to review this paper. The authors examined the influence of perceived social norms and beliefs about contraception on contraceptive use among married adolescents and young women in Ethiopia. Data is obtained from a community survey of 3039 young married women aged 14-24 years. A multivariate logistic regression analysis was used to identify factors associated with contraceptive use.

General comment:

The topic is a very interesting one that is relevant to family planning policies and programmes. There is a growing body of evidence on the link between perceived social norms/contraceptive beliefs and contraceptive use. Although there is merit in the contribution to knowledge, the paper has some conceptual flaws in the analysis and presentation of the results that should be fixed before consideration for publication. Authors included in their analysis of the effects of beliefs on contraceptive use, participants who are not aware of any contraceptive method. This introduces biases in the results. It is not possible to evaluate someone's beliefs and use of contraceptives when they are not aware of it. Analysis of the link between beliefs and contraceptive use should be restricted to those who have ever heard of contraception. It is not clear what study design was used. The study cannot be generalized given its weak design. There are a lot of grammatical errors that should be corrected by a language expert for it to meet publication standards.

Specific comments

Title:

The title of the paper should be written in a proper way highlighting its core content. Currently, it sounds more like a conclusion of the study rather than a title. It should be revised!. The title includes the text‘…in rural Ethiopia’ yet the sample includes participants from urban settings.

Abstract

There is a lack of clarity on how the association between outcome and independent variables are reported. Report only factors associated with contraceptive use.

Introduction

Outlining a conceptual model would be useful. The authors should also highlight key hypotheses to be tested in the study.

Methods:

It is not clear why the study computed a sample size of 1566, yet all 3102 young women in the study area were interviewed. It does not add value to calculate the sample size when a census is used. There need to clarify why all young women were interviewed instead of the number that was sampled.

The inclusion of place of residence, rural vs. urban, is problematic given that the urban sample size is negligible. The result is greatly biased given that the sample was not stratified to allow for comparison between rural and urban.

There is a high correlation between age and number of children that might affect the results when these two variables are included in the regression model. Also, adolescents <19 years are more vulnerable and are not as exposed compared to young women 20-24. The study can be strengthened by comparing participants <19 years with those aged 20-24 years

Result

Table 2: Instead of bi-variate logistic regression, do a simple comparison between contraceptive users and non-users by perceived social approval and beliefs using column totals. It also important to compare the mean scores of index indicators between users and non-users

Table 3: The title is ‘Multivariate logistic regression…’ However, there are some bi-variate results in columns 2&3. These should move to Table 2.

It is not clear which variables are controlled in the multivariate model. This makes it very difficult to infer the effects of perceived social norms and beliefs on contraceptive use. A more precise way to handle this would to running a separate model with the main independent variables without controls and another with the controls.

Review how the logistic regression results are reported. There seems to a confusion between the outcome and independent variables in the way the odds are reported. It is, therefore, very difficult to understand the magnitude and the direction of the effect of the independent factors on the outcome.

Reviewer #2: Comments for manuscript

Low contraceptive utilization among young married women is associated with perceived social norms and believes in contraceptive myths in rural Ethiopia

I believe it is well articulated and useful manuscript. My comments are, in the result section mean and standard deviations should be reported rather than SE.

Discussion: there is low contraceptive utilization in your study area even compared to the surrounding areas. You tried to tell us the presence of persistent socio-cultural norms that encourages large family size and then non-use of contraceptives methods at young age in rural setting. But the utilization is still lower than other rural areas. I suggest to find out more on the possible factors that contributed low utilization in your study area.

Reviewer #3: 1. Introduction: In the final statement of the introduction, in which you describe the aim of the study, it would be beneficial to describe this in more detail, so that you are very clearly stating the aim and the scope of the paper. Stating that the aim is to assess contraceptive behavior is perhaps too broad. Please also see below comments on pieces that could be elaborated on in the introduction, specifically the main independent variables.

2. Study setting: The description of the study site is very useful. It would be helpful to list the statistics you listed for the site for Ethiopia in general, so we can compare it to the average for the country. This will help to put your findings in context.

3. Methods and materials: It would be helpful to clarify how the sample was actually chosen. This section on sampling would benefit from the actual equation used with the inputs provided (contraceptive utilization, precision, design effect, and non-response). Why were all women included if the sample size was far exceeded? Were women contacted in their homes (was this a household survey?) Additionally, since half of the sample had no education, it may be useful to clarify how written informed consent was obtained for those who may not be able to read/write.

4. Variables and measurements: It would be very helpful to understand whether these injunctive norms and descriptive norms fit into a conceptual framework of some sort. How are these norms theorized to affect behavior? It would be very helpful to have a description of these norms/their expected effect on behavior in the introduction section of this paper, to help frame the research you conducted to the audience. Please also specify what all of the response options are for each of the norm and myths and misconception variables.

Did you hypothesize any sort of relationship between your two main predictor variables? It would be helpful to explain how you think the norms as well as the belief in myths/misconceptions might be related, in the introduction. Did you predict that one would be more important than the other, or that while they might be independently associated with the outcome, one would no longer be significant in multivariate analyses?

There are a lot of scale variables included, especially for variables that are not main predictors for the model. You may consider reassessing whether all of these are needed. Additionally, if you decide to keep them all, please elaborate on the items included in the contraceptive knowledge scale.

5. Data analysis: Is table 2 necessary for helping to understand the paper? I didn’t understand the purpose of this analysis from the description in the methods, perhaps because you had already described how the scales were calculated in the previous section of the methods. The Cruide ORs Table 2 may be too much information, and could be considered for an appendix if you decide it is needed. If it is needed, please elaborate on its purpose more in this section of the methods. I also don’t think you need to refer to the table numbers in the methods section.

The sentences where you describe that the scale variables were all included as continuous variables in the model is confusing because you describe how these variables were developed/coded in the variables and measurement section. I think you could put these sentences in the variables section instead.

The data analysis section should also clearly state that multivariate logistic regression was conducted, I don’t think this statement was included.

6. Results: The frequencies for age in Table 1 do not add up to 100. If there are missing data, please clarify this. On the other hand, the frequencies add up to more than your total sample size. Please clarify.

For the duration of continuous utilization, is that among current users only?

I don’t understand the purpose of the Cruide ORs from Table 2 in the body of the paper, perhaps it could be included in an appendix.

7. Results: The text describing Table 3 needs to be heavily revised. The odds ratios are not described in the correct way – the odds are of current contraceptive use, not of the background characteristics. Please revise here and in the abstract and discussion as well. Please also continue to be very clear about the outcome and include “current” in contraceptive use.

It would also be helpful to show the reference groups for all variables, even those with 2 categories. Then you could also add the Frequency(%) of contraception for each variable. I would also put the main predictor variables at either the beginning or the end of the table so they stand out.

8. I think the discussion clearly explores a lot of the main findings from the results. In the paragraph on descriptive norms, in the second sentence, it’s unclear whether the authors are arguing that it’s a misperception that most young women aren’t using contraception, when this study showed only 14% were using. Please elaborate on this possible reason women aren’t using. As I mentioned above, it would be helpful to elaborate on the relationships between these two norms as well as the relationship between norms and believing in myths. Please also spend a bit more time elaborating on suggested interventions and future research, perhaps among positive deviants.

I’m not sure I understand this sentence in the limitations: “Additionally, it could be argued that the positive association between contraceptive use and subjective norm may be due to contraceptives users may more likely to perceive others’ approval than who were not using.” Please elaborate.

Minor/Other:

Was there a minimum age for inclusion in this study?

Figure 1 is very hard to read.

I think this study would strongly benefit from a copy-edit for clarity, grammar, and minor issues with formatting in the text (this, along with the description of the ORs as mentioned above is the reason I selected No for Question 4).

PLOS One author guidelines state that contacting the corresponding author for data is not sufficient to meet their data availability guidelines.

Low contraceptive utilization among young married women is associated with perceived social norms and believing in contraceptive myths in eastern Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

I believe the manuscript has greatly benefitted from most changes. One of the referees agrees with the changes, referee 3 has not answered but I believe that most of the comments have been taken. Making the data available is also a great move that can help increase the visibility of the article.

  1. One of the characteristics that set apart this analysis from others is the focus on young AND married women. There should be some reference on pressure to procreate once married (i.e: https://doi.org/10.20897/femenc/5918, https://doi.org/10.1017/S0021932000003552). When this is understood, the low contraceptive prevalence of this group is understood better: they want to have children, particularly their first child. Probably the “policy” recommendation would not be so much “use contraceptives after getting married” but “marry later” given this cultural association. This should be highlighted to understand the context of such low contraceptive use as commented by reviewer 3.
  2. Also, in that respect, it would help to give comparable statistics on contraceptive prevalence for a similar group in Ethiopia from DHS. [I have seen you do it in the discussion comparing with DHS2016 in l. 329-330, I still give the data I looked for MiniDHS2019] For instance, it can be computed from the MiniDHS2019 (https://dhsprogram.com/pubs/pdf/PR120/PR120.pdf). It shows 36.5 prevalence for 474 currently married women 15-19 and 52.2 prevalence for 951 married women 20-24. Based on this a proportion for married women 15-24 can be estimated and provided as a reference. Indeed CP is very low in this region. While DHS does not provide a figure for Kersa, CP is not low in Oromia (40.7 compared to 41.4 nationally). However, neighbouring Ethiopia Somali shows only has 3.4 CP. Is there some clear a priori reason for this low uptake?
  3. Differences could also arise due to a different protocol in asking about contraceptive use. This should be acknowledged somewhere as a limitation since the DHS protocol is the standard for measuring CP internationally. Difference might lie in that DHS, before asking about use, asks about knowledge of each method.
  4. In contrast, line 333-334 is too vague: “the persistent socio-cultural norms that encourages large family size and then non-use of contraceptives methods at young age in rural setting of developing country”. There are many rural setting in developing countries where it is not the case. Also phrasing in singular form is not correct. Maybe “the persistent socio-cultural norms that encourage large family size and then non-use of contraceptive methods at young ages in this rural setting”
  5. There is no clear information on when the survey was carried out. That should be made clear.
  6. I also see missing data in the dataset. I guess most correspond to women that are not married. How handling of missing data was carried out should be mentioned in the methods section.
  7. I understand your argument of multicollinearity of age and parity, also raised by referee 1, but for the reason given above (pressure to become mother), it would be good to include at least a variable distinguishing ever-mothers. One would expect the variables of age lose importance after including it, but it is ok. Also much lower CP for non-mothers would be expected. Please include the variable in the multivariate analysis since non-mothers are less likely to use contraception. Note that l.205 says you are controlling by parity which seems not to be the case (after the addition of the variable, it will).
  8. The title has been changed but it still does not read correctly. “believing” should be “belief”, and it still reads too long. I would suggest “Low contraceptive use, perceived social norms and belief in contraceptive myths among young married women in Eastern Ethiopia”.
  9. There is no need to put all results in the abstract, just the main ones, in lines 45-53.
  10. The text would still requires copy-editing. Some suggestions in that respect, focusing in the abstract, but there is a need to check everything, particularly the discussion.
  • l. 39-40: “aged 14-24” instead of in the age-group 14-24.
  • L. 45: Remove “the” in the “the perceived social approval”
  • L. 56: Remove “the” in “the sociocultural…”.
  • L. 57: Replace “are necessary” which does not stem from the analysis, and “to improve”, which assumes a value judgement regarding contraceptive use, with “could increase” or something similar.
  • Avoid “unmet needs” (l. 73), use “unmet need”.
  • L. 336: suppress “norm”
  • L. 339-40: Rephrase. “Despite” does not make sense. Also “imperative” is too strong.
  • L. 364 should be “mothers”
  • L. 366: suppress “be”
  • L. 367-68 do not make sense. Rephrase.
  • L. 375: Again the problem with “belief” (noun) and “believe” (verb) but the other way round. It should be “believe in” instead of “belief the”.
  • L. 379: Again rephrase “developing countries”. This example is not representative. Just suppress “in developing countries”. Also “which even accompanied by” is wrong. In general this paragraph needs copy-editing.
  • L- 388 Also check all this page for grammar. Example: “This tended to resulted” maybe “result”. You can use “Grammarly.com” or a similar tool that will indicate all these problems.
  • L. 410: Socio-cultural, not social-cultural. Also commas missing before mainly and after myths.

Low contraceptive use, perceived social norms and belief in contraceptive myths among young married women in Eastern Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Some of the issues raised have been addressed but others have not. In particular, two points remain:

3- Possible limitation, differences with DHS protocol.

You argue that this is not an issue, but I cannot judge this based on the information I have. I am concerned, for instance, about probing questions regarding knowledge that can make a difference (and are known to make a difference). Please provide a copy of the questionnaire so that this can be assessed. If the protocol is exactly the same, please make it clear in the paper If it is different, acknowledge that as a possible limitation and describe in what ways it is different.

7- I insist in the model with an ever-mother covariate. You could include both models for comparison, but I think it is even more important after showing the strong bivariate link, As I said there are important reasons to include it: married youth with no children are very likely to desire getting pregnant and, therefore, not to use contraception.

Please submit your revised manuscript by Dec 05 2020 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org.

Revision 3

3- Possible limitation, differences with DHS protocol.

You argue that this is not an issue, but I cannot judge this based on the information I have. I am concerned, for instance, about probing questions regarding knowledge that can make a difference (and are known to make a difference). Please provide a copy of the questionnaire so that this can be assessed. If the protocol is exactly the same, please make it clear in the paper If it is different, acknowledge that as a possible limitation and describe in what ways it is different.

Response: We understand your concern and describe the similarity of our questions with the DHS questionnaire in the revised manuscript. A copy of the DHS questionnaire is found on the following website: http://dhsprogram.com/pubs/pdf/FR328/FR328.pdf . The questionnaire specific to contraception is indicated on ‘APPENDIX E’, under the title ‘SECTION 3. CONTRACEPTION’ and page 402 or pdf page 435

7-I insist in the model with an ever-mother covariate. You could include both models for comparison, but I think it is even more important after showing the strong bivariate link, As I said there are important reasons to include it: married youth with no children are very likely to desire getting pregnant and, therefore, not to use contraception.

Response: We appreciate your concern and addressed it by including both models (age and ever-mother status) based on your suggestion.

Low contraceptive use, perceived social norms and belief in contraceptive myths among young married women in Eastern Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

There were two issues left:

- ISSUE 1: ​3- Possible limitation, differences with DHS protocol.

You argue that this is not an issue, but I cannot judge this based

on the information I have. I am concerned, for instance, about

probing questions regarding knowledge that can make a

difference (and are known to make a difference). Please provide

a copy of the questionnaire so that this can be assessed. If the

protocol is exactly the same, please make it clear in the paper If

it is different, acknowledge that as a possible limitation and

describe in what ways it is different.

RESPONSE: You are giving me a link to the DHS questionnaire. I know that one. What I was asking was to provide a copy of YOUR questionnaire. I am still unable to assess what I was mentioning. And, as I said, it is not a question of simmilarity. If it is not identical in the protocol (example: probing with knowledge of methods, ...) you have to acknowledge that as a possible limitation and describe in what ways it is different. That is still missing.

ISSUE 2: I insist in the model with an ever-mother covariate. You could

include both models for comparison, but I think it is even more

important after showing the strong bivariate link, As I said there

are important reasons to include it: married youth with no

children are very likely to desire getting pregnant and, therefore,

not to use contraception.

RESPONSE: We appreciate your concern and

addressed it by including both models

(age and ever-mother status) based on

your suggestion.

I welcome the addition of the model. You must see how important is the coefficient on ever-mother. But, still, the model is not commented in the text. You should. Please go back to my original comments on the reason for my insistence with including the variable:

I understand your argument of multicollinearity of age and parity,

also raised by referee 1, but for the reason given above (pressure

to become mother), it would be good to include at least a variable

distinguishing ever-mothers. One would expect the variables of

age lose importance after including it, but it is ok. Also much

lower CP for non-mothers would be expected. Please include the

variable in the multivariate analysis since non-mothers are less

likely to use contraception. Note that l.205 says you are

controlling by parity which seems not to be the case (after the

addition of the variable, it will).

Please comment on this in the main text. Please also change the names of the models that do not read well.  You can call them model 2a and model 2b or models 2 and 3 or something like that.  Please also add some measure of model fit for models 1, 2a and 2b that could be used to choose among them, such as AIC, BIC, Nagelkerke pseudo R-squared, etc. Make sure that the results reported throughout the text refer to the best model and make it clear in the text.

Low contraceptive utilization among young married women is associated with perceived social norms and believing in contraceptive myths in rural Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

There were two issues left.

1. Regarding the questionnaire, you convinced me that you were following the same DHS protocol.  I suggest changing the current sentence "We followed the DHS questionnaire protocol in adapting the questions used to assess contraceptive knowledge and utilization" with something more to the point "We followed the DHS questionnaire protocol for questions on contraceptive knowledge and utilization"

2. I think my instructions were clear "Please also add some measure of model fit for models 1, 2a and 2b that could be used to choose among them, such as AIC, BIC, Nagelkerke pseudo Rsquared, etc. Make sure that the results reported throughout the text refer to the best model and make it clear in the text.". 

What you have done is to include a sentence that reads confusing "We used Akaike’s information criterion (AIC), Bayesian information criterion (BIC), and Pseudo R2 in building the regression models. The model with low AIC and BIC, and high Pseudo R2 scores were considered as the final model. Additionally, the model fitness tested using the Hosmer–Lemeshow goodness-of-fit tests". There is no other mention of AIC, BIC or Pseudo R2 in the text. What is going on?

I will be more clear:

1. Choose ONE model selection criterium. I'd suggest AIC.

2.. Report in table 2 the AICs for the different models. In particular look at what model is best according to the criterium: model 2a or model 2b, and make notice of it in the main text.

3. Make sure that all references in the text and abstract to results from the models refer to the best model from step 2.

COMEBACK ISSUE: The title changed again. It is OK except for "believing" that should be BELIEF.

NEW ISSUE: Since you are highlighting in the paper the connection with the variables on social pressure and contraceptive myths,  I see that in the "limitations" paragraph (399-416) there is no mention regarding possible alternative interpretations of the contraceptive myths variable which are clearly there in an observational setting such as post-hoc rationalization. In particular you should add something along these lines "Regarding the impact of belief in contraceptive myths, it cannot be ruled out that the relationship is not causal but due to post-hoc rationalization of a refusal to use contraception".

Please submit your revised manuscript by Jan 04 2021 11:59PM.

Low contraceptive utilization among young married women is associated with perceived social norms and belief in contraceptive myths in rural Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Congratulations on a much improved manuscript. The vast majority of issues regarding substance have been addressed. There are important problems regarding readability, though. This is important since a poorly written manuscript will be much less influential.

A first problem of factual incorrection that needs to be rewritten is this:

72 Previous studies have reported the highest levels of unmet need, and the lowest and interrupted

73 contraceptive utilization among young married women in developing countries [8].

The cited study does not say what is being said here. It is not a comparative study, it only studies unmet need of young women. In addition, it is not true that young married women have the highest unmet need levels. For instance, https://www.demographic-research.org/volumes/vol38/45/38-45.pdf show that sexually active unmarried young-women have higher levels of demand and unmet need in most DHS surveys than their married counterparts. If we look at unmet need by age in Ethiopia, for instance DHS 2016, in table 7.10.1 we find that unmet need is highest for married women 35-39, and in table 7.10.2 the same applies to all sexually active women. Table 7.10.2 indicates that 15-19 and 20-24 actually have the lowest levels of unmet need.

Regarding editing, I provide a detailed assessment of problems. In particular the section on variables and measurement is written very poorly. Throughout the text there remain problems of grammatically incorrect sentences. I give you a detailed list of problematic sentences and proposed solutions, but the final text must be checked throughout afterwards. I also insert a couple of problems that are not only grammatical.

Low contraceptive utilization among young married women is associated with perceived social norms and belief in contraceptive myths in rural Ethiopia

PLOS ONE

Dear Dr. Dingeta,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

There are still problems of readability. In addition, you should have given a point by point response to the comments. Otherwise it makes revision very difficult. There are still many sentences that are incomplete or with no agreement in number among nouns and verbs, or missing (or with superfluous) pronouns. After a reread I include some, but this is still a problem. These are some of the issues remaining but you are encouraged to copy-edit your article further.

Despite the increasingly wider availability of contraception and the level of needs

33 in rural Ethiopia,

I asume you mean “Despite the increasingly wider availability of contraceptives and the high levels of potential demand [or unmet need] for family planning in rural Ethiopia, …”

Substantial proportion of young married women in low and middle-income countries are at risk of

73 unintended pregnancy due to low contraceptive utilization than their adult counterparts. Young

74 women in the region also often used short-term methods that related to high failure and

75 discontinuation (8, 9).

The sentence is not grammatically or factually correct: what does the “than” mean, what is the comparison? As I said in the previous revision, what matters here is unmet need, and the levels are not highest among young married women. Also, women over 18 are adults. As it was discussed it is not true that levels of unmet need are highest. The second sentence is also missing a verb (I guess are related to higher ..).

Change proposed to old line 89-93 only partially adopted (missing the second part), and it now reads funny.

New line 102: studies have shown, not “studies have been shown”

New line 203: higher score indicates high believe in the myths or had 204 misconception about contraceptive methods.

Should be “a higher score indicates strong belief in the myths or  misconceptions regarding contraceptive methods.”
