This study was a clinical trial (IRCT20151103024866N16), and the statistical population included all married women aged 18 to 45 years who were referred to health centers in Kerman, a city in the south of IRAN; to receive care and family planning counseling. The ethical committee of the university approved the study, and all women signed an informed consent before enrollment. Convenience sampling was used for participants who were women whose husbands did not cooperate in choosing a contraceptive method but complained and made excuses about every method the woman used. These women were under the coercion of spouses in contraception use, according to World Health Organization (WHO) guidelines (refusal of specific contraceptive methods, or insistence on a particular type of method, or resistance to contraceptive counseling, history of repeated pregnancies, or request for a medical termination, and insistence on tubal ligation or insistence on reversal of tubal ligation).

The sample size needed to achieve a reliability of 1.96 and study power of 85%, based on the results of the study by Nabavi et al. (2019), was approximately 6 participants for each group; however, 27 people were selected to increase the study capacity and compensate for the loss of samples.
Because the samples were divided into 3 groups, the final sample size was 81 people. The identified women were included in the study if they consented to participate and had the inclusion criteria. Then, all identified persons were randomly divided through a table of random numbers into three groups: control, psychoeducational counseling, and the IMB model.The inclusion criteria were married women in Kerman aged between 18 and 45, who were the only spouse of their husbands and whose spouses were present in Kerman during the intervention; had at least one of the criteria for violence against women regarding contraceptive methods according to the checklist of the WHO; consented to participate in the study; were literate; had been married for at least 1 year; had no known mental illness; and had access to a smartphone (due to online education) and the ability to use it. The exclusion criteria included pregnancy or participating in other psychological counseling classes simultaneously. Reasons for discontinuation were absence in two or more of the counseling sessions, and unwillingness to continue participation.
The research tool consisted of demographic information, a checklist for evaluating the contraception method requested by the spouse (WHO), and a special researcher-made questionnaire on contraceptive methods and sexual satisfaction. This questionnaire was prepared based on scientific articles.

First, the study's objectives were explained to women who met the inclusion criteria, and, if they wished to participate, written informed consent was obtained from them. All three groups completed the questionnaire on sexual satisfaction, specific contraception methods, and contraception type before the intervention, immediately after, and 1 month after the intervention. The study's objectives were first fully explained to participants to prevent information exchange between group members. Introduction sessions were held separately for each group. Given that information exchange is possible in cyberspace, to prevent information exchange between participants, after dividing them into 3 groups (control, psychoeducational, and IMB), a time interval of 2 months was considered for each group. First, a pretest was completed for the control group, and posttests were done 1 month later and 1 month after the initial posttest. Then a pretest was done for the psychoeducational group; the initial posttest was done after the three virtual counseling sessions in Skyroom; the final posttest was completed 1 month after the intervention. The total time spent implementing the intervention and completing the questionnaires was 6 months. In the control group, the clinic midwife provided all routine training. In the intervention group, psychoeducational counseling sessions were held according to a unique package of counseling sessions in 3 90-minute online sessions 1 week apart. In the IMB model intervention group, counseling sessions were held according to a specific package, in 4 online sessions, 120 to 190 minutes each 2 sessions per week, and all these sessions were held by the same person (the researcher). Finally, immediately after the intervention and 1 month later, the participants in the 3 groups completed the questionnaire. The psychoeducational counseling and IMB program packages were designed, prepared, and implemented using various resources 216 people were surveyed to participate in the study, of which 135 were either not eligible or unwilling to participate in the study. Eighty-one people were included in the study. By lot, they were divided into three groups (one was a control group and two were intervention groups). Since the intervention was performed on and offline, we did not have any sample drop, and, finally, the analysis was performed on 81 people. Data were analyzed using the IBM SPSS Statistics for Windows, version 22 software (IBM Corp. Armonk, NY, USA). Quantitative variables were described by mean and standard deviation, and qualitative variables were defined by frequency and frequency percentage. The Kolmogorov-Smirnov and Shapiro-Wilk tests were used to evaluate the normality of dependent variables (sexual satisfaction and changes in contraceptive methods). Due to the abnormality of data distribution, the Friedman test was used to examine the trend of changes. The nonparametric equivalent of one-way analysis of variance, Kruskal-Wallis, was used for comparison (
