بررسی رابطه خودپنداره جنسی با عملکرد جنسی و عزت نفس در زنان مبتلا به اختلال واژینیسموس

Background and Aims: Vaginismus is one of the most common sexual disorders among women. The present study aimed to investigate the relationship between sexual self-concept and sexual function and self-esteem in women with vaginismus disorder. Materials and Methods: In this study, 124 women with vaginismus referred to Family Health Clinic, and Obstetrics and Gynecology Clinic in Tehran were studied by random sampling method. Data gathering tool included Multidimensional Sexual Self-Concept Questionnaire (MSSQ), Female Sexual Performance Index (FSFI), and Rosenberg Self-Esteem Questionnaire (RSE). Ethics and confidentiality of answers were observed and all stages of the present study were performed according to ethical standards. Results: Findings revealed that some components of sexual self-concept including sexual anxiety, sexual self-efficacy, motivation to avoid high-risk sexual intercourse and sexual depression (at the level of a = 0.01) and sexual optimism, self-blame - sexual problem, sexual satisfaction (at the level of a = 0.05) were significantly correlated with sexual function. Indeed, sexual anxiety, sexual problem management, sexual self-esteem, sexual schemas, fear of sex (a = 0.01) and sexual self-efficacy, sexual motivation, sexual satisfaction, sexual depression (a = 0.05) were appreciably associated with self-esteem. Conclusion: Findings indicate the relationship between some components of sexual self-concept and sexual function and self-esteem. Also components of sexual anxiety, sexual self-efficacy, sexual awareness, motivation to prevent high-risk sexual intercourse, sexual anxiety, sexual control, sexual motivation, sexual self-esteem, other sexual control power, and sexual problem prevention have the largest share in explaining sexual function. Also sexual anxiety has the largest role in explaining self-esteem.زمینه و اهداف: یکی از اختلالات جنسی شایع در میان زنان واژینیسموس است. هدف از این مطالعه تعیین رابطه خودپنداره جنسی با عملکرد جنسی و عزت نفس در زنان مبتلا به اختلال واژینیسموس است. مواد و روش‌ها: در این مطالعه ، ۱۲۴ نفر از زنان مبتلا به اختلال واژینیسموس مراجعه کننده به کلینیک سلامت خانواده و مطب پزشک زنان و زایمان واقع در شهر تهران به روش نمونه‌گیری تصادفی مورد مطالعه قرار گرفتند، ابزار گردآوری داده‌ها شامل پرسشنامه چندوجهی خودپنداره جنسی (MSSQ)، شاخص عملکرد جنسی زنان (FSFI) و عزت نفس روزنبرگ (RSE) بوده‌اند. تمامی مراحل مطالعه حاضر طبق موازین اخلاق در پژوهش و محرمانه بودن پاسخ‌ها اجرا گردید. یافته‌ها: یافته‌های پژوهش نشان داد که برخی از مولفه‌های خودپنداره جنسی؛ اضطراب جنسی، خودکارآمدی جنسی، انگیزه برای جلوگیری از رابطه پرخطر جنسی و افسردگی جنسی (01/0=a) و خوشبینی جنسی، خودسرزنشی مشکل جنسی، رضایت جنسی (05/0=a) با عملکرد جنسی معنادار بوده و همچنین اضطراب جنسی، مدیریت مشکلات جنسی، عزت نفس جنسی، طرح‌واره‌های جنسی، ترس از رابطه جنسی (01/0=a) و خودکارآمدی جنسی، انگیزه جنسی، رضایت جنسی، افسردگی جنسی (05/0=a) با عزت نفس معنادار می‌باشد. نتیجه‌گیری: یافته‌های پژوهش بیانگر ارتباط برخی از مولفه‌های خودپنداره جنسی با عملکرد جنسی و عزت نفس است. همچنین مولفه‌های اضطراب جنسی، خودکارآمدی جنسی، آگاهی جنسی، انگیزه برای جلوگیری از رابطه پرخطر جنسی، دغدغه جنسی، نظارت جنسی، انگیزه جنسی، عزت نفس جنسی، قدرت کنترل جنسی دیگر، پیشگیری از مشکل جنسی بیشترین سهم را در تبیین عملکرد جنسی داشته‌اند و همچنین اضطراب جنسی بیشترین سهم را در تبیین عزت نفس داشته است

Factor structure, Validity, and Reliability of General Health Questionnaire (GHQ-28) in Iranian Adolescents

Investigation of Factor structure, validity, and reliability of general health questionnaire (GHQ) in Iranian adolescents was the purpose of present study. Study design was descriptive and 1497 high school students (789 girls and 708 boys) from Qom, Damghan, and Bojnoord cities were selected using cluster sampling. General Health Questionnaire (GHQ) as the main questionnaire, and General Anxiety Index (GAD-7) and Personal Wellbeing Index- School Children (PWI-SC) were used to assess convergent validity. Results of explanatory and parallel factor analysis revealed three factors predicting 36.36 present of variance in scores of general health questionnaire. Indexes of confirmatory factor analysis showed good fitness of three-factor model and in general 8 questions were removed. Correlation between three dimensions of 20 item general health questionnaire with main questionnaire was strong and significant, with GAD-7 was moderate and with PWI-SC was strong (moderate for depression dimension). Cronbach's alpha value for dimensions and total score of questionnaire were acceptable and test-retest coefficients were strong. 20 items general health questionnaire with vitality and energy, anxiety and somatic symptoms, and depression was obtained

Basic Evaluation of Validity and Relia-bility of Personal Welfare (Life Qual-ity) Index, Student Copy (PWI-SC)

Some of indices which are provided for measurement of life quality in general population are not applicable for all groups such as children and individuals with cognition disorders. In order to cope with this limita-tion, after some researches, personal welfare (life quality) index (PWI) was developed in Australia. Subsequently, its similar version was de-signed for student population of 12-year to 18 year old and its psycho-metric features was evaluated. So, the purpose of this study is examina-tion of the mentioned scale psychometric features among Iranian student population. Statistical population was all of high school students in Boj-nourd. A sample of 563 students was selected by cluster sampling. In this study, Personal Welfare Index Student Copy (PWI-SC), General health Questionnaire (GHQ-28), and Generalized Anxiety Disorder 7-item (GAD-7) were used. Also, Pearson correlation, confirmative heuris-tic factor analysis, regression and t-test for independent groups were ap-plied. Findings showed that PWI-SC based on Cronbach Alpha (0.81), two-item scale Cronbach Alpha (0.69 and 0.62), and correlation coeffi-cient related to its retest (0.87) have appropriate reliability. Also, relia-bility of scale was evaluated by correlation to other questionnaires: GHQ and GAD-7. Factor analysis of the scale in Iranian student sample indi-cates its saturation by one factor. Generally, personal welfare index stu-dent copy (PWI-SC) has appropriate psychometric features considering the methodology limitations of this study
