Psychometric Characteristics of the Iranian Version of the Motives for Online Gaming Questionnaire (I-MOGQ).

Objective: The growing popularity of computer games has attracted the attention of researchers in this field. The underlying psychological motives of gamers are important to prevention of disorders related to online gaming. This study was aimed at evaluating the psychometric characteristics of the Iranian version of the Motives for Online Gaming Questionnaire (I-MOGQ) and its association with Internet Gaming Disorders (IGD). Method : Four hundred and fifty-two Iranian adult gamers (mean age = 21.5 years, SD = 4.14) voluntarily responded to the anonymous survey online. All participants in this study were males. The questionnaires used in this study were MOGQ and IGD Scale. We performed confirmatory factor analysis (CFA) for MOGQ. Also, the correlation between MOGQ and IGD was evaluated. Results: CFA supports the construct validity of the questionnaire (RMSEA < 0.08). Cronbach's alpha, as an indicator of internal consistency of the questionnaire, was 0.91 (Social = 0.85, Escape = 0.84, Competition = 0.83, Coping = 0.79, Skill Development = 0.89, Fantasy = 0.85 and Recreation = 0.83). Also, the scale displayed adequate convergent validity, as shown by significant positive correlations with IGD scores. The highest correlation was found with the Escape motive (0.57) and the lowest was found with Recreation (0.15). Conclusion: This study showed that the Iranian version of the MOGQ is a valid and reliable scale for identifying the motives for online gaming among young adults.

According to multiple regression analysis, it was found that satisfaction with the partner, satisfaction with marriage, economic status, emotional relationship, tobacco use, psychiatric disorders have significant relationships with sexual frequency in couples.Conclusions: According to the results, it can be concluded that there were no significant differences in sexual desire, frequency, pleasure and request in married couples during the COVID-19 outbreak.

The association of dietary macronutrient quality indices with depression and anxiety symptoms and quality of life in Iranian adults: The LipoKAP study

BackgroundMacronutrients' quality may impact differently on mental health and quality of life (QOL). This study aimed to investigate the potential relationship between the carbohydrate quality index (CQI), fat quality index (FQI), protein quality index (PQI), the affective mental symptoms and QOL among Iranian adults. MethodsThe LipoKAP is a cross-sectional study, conducted with 2456 adults in Iran. A validated food frequency questionnaire was used to evaluate usual dietary intakes. A validated Iranian version of the Hospital Anxiety and Depression Scale was used to assess the severity of anxiety and depression. QOL was assessed by EQ-5D. ResultIn the fully adjusted model, participants in the highest tertile of CQI had lower QOL than those in the lowest tertile (OR = 1.35; 95 % CI: 1.06, 1.73). Individuals in the top tertile of FQI (OR = 0.71; 95 % CI: 0.55, 0.91) and PQI (OR = 0.78; 95 % CI: 0.60; 1.01) were less likely to report lower QOL than those in the bottom tertile. An inverse association was found between PQI and depressive symptoms (OR = 0.72, 95 % CI: 0.55, 0.95), but not for CQI and FQI. LimitationsThe cross-sectional design of the study and the use of a memory-based dietary tool may limit the generalizability of our findings. ConclusionHigher PQI was associated with lower risk of depressive symptoms and having a low-quality life. Although CQI and FQI were not related to depressive and anxiety symptoms, higher values of FQI were associated with better QOL, while CQI showed an inverse association.

Psychometric properties of Persian version of depression literacy (D-Lit) questionnaire among general population

BackgroundThe prevalence of depression in society is increasing and there is a need for a suitable tool to assess the health literacy of people in this field. This study was conducted to evaluate the psychometric of the Iranian version of the depression literacy (D-Lit) questionnaire.MethodsThis cross-sectional study was conducted on 845 participants with a proportional stratified sampling method. First, the translation and cultural adaptation of questionnaire was performed. Then, the validity of D-Lit was assessed by face validity, content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). The reliability of D-Lit was assessed by the Cronbach’s alpha coefficient and McDonald omega coefficient.ResultsBased on the results of EFA, 5 factors emerged with eigenvalues of greater than 1, which accounted for 56.30% of the variance. Based on the results of CFA, one question was deleted and the results of goodness fit indexes confirmed the model. Cronbach’s alpha coefficient and McDonald omega coefficient for D-Lit questionnaire were 0.890 and 0.891, respectively. Finally, D-Lit questionnaire with 21 questions and 5 subscales of Knowledge of the psychological symptoms (5 items), Knowledge about the effectiveness of available treatment methods (4 items), Knowledge about cognitive-behavioral symptoms (6 items), Knowledge about taking medications and their side effects (4 items), and Knowledge of the severity of the disease (2 items) were confirmed.ConclusionThe results of this psychometric evaluation confirmed the Persian version of D-Lit questionnaire with 21 questions and 5 subscales is an appropriate tool for measuring people's literacy about depression.

The relation between MIND diet with psychological disorders and psychological stress among Iranian adults

BackgroundGiven the role of dietary antioxidants in relieving depression, anxiety, and stress, as well as studies on the beneficial effects of the Mediterranean and Dash diets separately on these problems, in this study, we examine the relationship between the MIND index (Mediterranean- DASH diet Intervention for Neurodegenerative Delay) as a combined indicator of the Mediterranean and DASH diet with psychological disorders such as depression, anxiety, and psychological stress among a large sample of the Iranian adult population.MethodsThis cross-sectional study was performed on 7165 participants of the enrollment phase of Yazd Health Study (YaHS) and Yazd Nutrition Study (TAMYZ) a valid 178-item semi-quantitative food frequency questionnaire (FFQ) was used to assess participants’ food intake. The MIND diet score was calculated based on participants’ dietary intakes obtained from FFQ. Also, the valid Iranian version of the Depression, Anxiety, and Stress Scale (DASS 21) was used to assess psychological disorders and stress. In addition, the association between the MIND diet and psychological disorders and stress was assessed through logistic regression.ResultsThe mean ± SD score was 3.33 ± 3.79 for depression, 2.99 ± 3.65 for anxiety, and 5.93 ± 4.70 for psychological stress. The mean score of MIND in this study was 7.56. After adjustment for after adjusting for age, gender, intake of energy, BMI, history of chronic disease, marital status, education level, smoking history, physical activity level, pregnancy or lactation, intakes of dietary EPA, DHA, and fiber, individuals in highest compared to the lowest quartile of MIND diet score had significantly lower odds of depression (OR = 0.62, 95% CI 0.40 – 0.96; P-trend = 0.02) and anxiety (OR = 0.61, 95% CI 0.41 – 0.91; P-trend = 0.01). However, no significant association was observed for psychological stress (OR = 0.57, 95% CI 0.28 – 1.14; P-trend = 0.83).ConclusionTherefore, it seems that following the MIND diet can prevent the possibility of these psychological problems. However, there is a need to design studies with more robust methodologies such as clinical trial studies.

The Effectiveness of Marriage Enrichment Training of TIME Plan on Improving Marital Intimacy and Women’s Psychological Security

Objective: This study aimed to investigate the effectiveness of the Training in Marriage Enrichment (TIME) plan on increasing marital intimacy and psychological security of married women. Methods: The present research was a quasi-experimental study with a pretest-posttest design with a control group. The study subjects (40 married women living in Mashhad City, Iran) were selected for the TIME plan with the available sampling method and according to the criteria for accepting couples. Then, they were randomly allocated to two equal groups. Of these, 20 were in the experimental group and 20 in the control group. The experimental group, along with regular medical care, received TIME plan for 8 weekly sessions of 2 hours (from May up to the end of July 2021) in the Psychology Clinic of Ferdowsi University of Mashhad, Mashhad City, Iran. The control group received only regular medical care in this period. Both groups responded to the Iranian version of the Bagarozzi marital intimacy needs questionnaire, and Maslow’s psychological security-insecurity questionnaire before the intervention (pretest) and immediately after the intervention (posttest). Results: After controlling the subjects’ age and education, the results of the statistical analysis showed a significant effect of the TIME plan on increasing the marital intimacy of women who were in the experimental group compared to the control group (P=0.001). Nevertheless, this plan did not increase women’s psychological security (P&gt;0.05). Conclusion: The findings of this research show the importance and impact of the TIME plan training on increasing women’s marital intimacy, but it does not increase women’s psychological security. Therefore, in marriage counseling and interventions, it is possible to use the educational package of the TIME plan to improve the relationship of couples and increase their intimacy.

Development and Validation of the Rhinoplasty Outcomes Evaluation (ROE) Questionnaire: An Analytical Study.

BACKGROUND:Rhinoplasty Outcome Evaluation (ROE) is an easy-to-use questionnaire that allows comprehensive assessment of rhinoplasty-related patient satisfaction. However, the normal values for this questionnaire are not known. Therefore, we aim to validate the ROE questionnaire adapted to Iranian culture.METHOD:In this cross-sectional descriptive study, the statistical population consisted of applicants for cosmetic surgery referred to Shahid Rajaee Hospital, Shiraz, Iran, in the autumn and winter of 2017. Two hundred individuals participated in this research by a convenience sampling method. The questionnaire (ROE) was translated to Persian and backward translated to English by independent medical extern Persian speakers with complete English proficiency. The data were analyzed using SPSS software version 23 using exploratory factor analysis. RESULTS:The findings showed that the Cronbach’s Alpha of composite reliability (CR) and average variance extracted (AVE); overall, values above 0.4 were favorable in this measure. In addition, the AVE ranged from 0.50 to 0.59, which confirmed convergent validity. The AVEs of each factor was higher than the squared correlations and confirmed discriminant validity within the constructs. In the presence of significant factor loadings and composite reliability greater than 0.70, convergence validity was confirmed. Furthermore, the higher AVEs for each factor were compared to the squared correlations to confirm discriminant validity.CONCLUSION:The Iranian version of ROE is a valid instrument to assess results in rhinoplasty patients.

Olfactory function trends in COVID-19 patients: a prospective cohort study

Background One of the most common symptoms in COVID-19 patients is olfactory and taste dysfunction. Aims/objectives This study aimed to evaluate the olfactory threshold, and identification using objective tests in the Iranian population. Material and methods The present study was a prospective cohort study conducted in 2020–2021 on clinically recovering COVID-19 patients. Olfactory function was evaluated at the baseline, 4–6 weeks, and 12 weeks later. Olfactory threshold assessment was performed using the Saba Sabalan kit. The Iranian version of the Pennsylvania Smell Identification Test (IR-SIT) was used for olfactory identification. The olfactory threshold was categorized as poor (<8) and good olfaction (≥8). Results In the present study, 111 patients were examined, including 55 men and 56 women (mean age 41.4 and 53.4 years, respectively). The mean olfactory threshold was better for men (7.2) than for women (6.6). Analysis showed age to have a negative relationship with good olfaction at baseline (OR = 0.93, p = .05). Using IR-SIT, only 29.7% had normal olfactory function. Using linear regression, smoking was found to be significantly related to baseline IR-SIT score (adjusted Beta <0.001, p = .03). Conclusions and significance Objective tests are appropriate methods for assessing olfactory dysfunction in COVID-19 patients. Further studies are recommended.

Psychometric properties and factor structure of the Iranian version of the Social Phobia Inventory (I-SPIN)

Introduction: Despite the high prevalence of social anxiety disorder and the necessity of conducting etiological studies, the existing measures of social anxiety lack robust factor structure due to methodological flaws, leading to doubtful results. Aim: The present study is aimed to investigate the factor structure, reliability, and convergent validity of the Iranian version of the Social Phobia Inventory (I-SPIN). Method: This is a cross-sectional, psychometric study. Two large samples (N1=1210, N2=228) have been selected with the convenience sampling method from the student population of the three different universities in Zanjan city (i.e., University of Medical Sciences, Azad, and Payame Noor University) who were studying in those universities from February to July 2020. CAQ-GE, BAI, BDI-II, and IUS-12 were used in the present study. Exploratory and confirmatory factor analysis were conducted using Mplus-7.4 and SPSS-26 was used to perform internal consistency and validity analyses. Results: Exploratory and confirmatory factor analysis revealed that the two-factor model best fit the data. Besides, the results indicated that the I-SPIN has a positive and significant correlation with anxiety-related measures (p&lt;0.01) and acceptable internal consistency (α=0.92). Conclusion: Considering the excellent psychometric properties and a robust factor structure of the I-SPIN in an Iranian college student sample, using this measure would improve the accuracy of future studies and help us broaden our knowledge of the underlying mechanisms of this disorder.

New Modification of Smell Identification Test for the Detection of Malingerers: A Pilot Experimental Study.

Background: A major problem with the University of Pennsylvania Smell Identification Test (UPSIT) is its poor sensitivity for malingering detection in a group of people familiar with the test mechanism. This study aimed to evaluate the modification of UPSIT to detect anosmia malingering.Methods: This was a pilot experimental study conducted in 2019 in Tehran. The participants were 60 healthy subjects classified into two groups of 30 people. The first group was requested to deliberately feign a negative result on the Iranian version of UPSIT, Iran Smell Identification Test (ISIT) (malingering group). The second group consisted of participants, who did not scratch the odorant part of ISIT during the tests (anosmia group). ISIT was modified in two steps. At each step, one incorrect option was deleted from the available choices. The number of each group’s answers, altered away from the correct choice, was then calculated and compared.Results: The coached malingering group participants were able to feign anosmia in the original ISIT exam. In the modified ISIT, the number of answers changed from correct to wrong during the second stage (from three available choices to two choices) was significantly higher in the anosmia group (P<0.001). In the ROC analysis, the area under the curve was 0.92 (P<0.001). The cut-off of 4.5 for this test showed 93% sensitivity, 82% specificity, and 90% PPV and NPV.Conclusion: The ISIT is not capable of detecting malingering in the coached participants, yet by deleting the choices step-by-step, the sensitivity and specificity of the test increased.

Long-Term Parallel Changes of Physical Activity and Body Mass Index in Different Predisposing Risk Trajectories of Obesity.

The long-term parallel changes of physical activity and body mass index (BMI) in the adult population are still unclear. The present study assessed the association between physical activity and BMI over time, considering obesity risk trajectory groups and sex strata. Total sample of 6897 adults was followed for an average of 12 years. The reliable and validated Iranian version of the Modifiable Activity Questionnaire measured physical activity. After determining the risk clusters in each reexamination using a 2-step cluster analysis, the latent growth curve modeling was used to identify distinct subgroups of individuals following a similar change of risk cluster over time. Latent growth curve modeling estimated the parameters of cross-sectional, prospective, and parallel associations. Three trajectories were identified, including stable low risk, unstable risk, and stable high risk. The results showed significant increases in BMI (kg/m2/year) for the stable low-risk trajectory group 0.478 (95% confidence interval [CI] 0.444 to 0.513), unstable risk 0.360 (95% CI, 0.324 to 0.396), and those in the stable high-risk trajectory group 0.255 (95% CI, 0.221 to 0.289). In cross-sectional -0.483kg/m2 (95% CI, -0.836 to -0.129) and parallel -0.93kg/m2 (95% CI, -1.862 to 0.00) estimations, significant statistical associations were observed in the stable high-risk trajectory group. The current results showed that changes in physical activity could slightly affect BMI only in stable high-risk adults.

Type 2 Diabetes Health Literacy Assessment Tool: Translation and Psychometric Evaluation of the Iranian Version

BackgroundAdequate health literacy can lead to self-care behaviors among patients with type 2 diabetes (T2D). Although there is an instrument for measuring the health literacy of patients with diabetes, there is no Persian version of the instrument in Iran.ObjectivesThe aim of this study was to translate the Chinese Health Literacy Scale for Diabetes (CHLSD) and evaluate the psychometric parameters of the Iranian version.MethodsIn this methodological study, using a standard forward-backward translation procedure, the original English language version of the questionnaire was translated into Persian. Face and content validity steps were performed for psychometric measurements. To perform construct (convergent) validity, a cross-sectional study was carried out with the participation of T2D patients admitted to the diabetes clinic (aged over 25 years old). To test the reliability, internal consistency was assessed by Kuder-Richardson (K-R) coefficient, and a test-retest was performed by Spearman correlation coefficient.ResultsA total of 283 patients with T2D (mean age: 52.4 years and standard deviation: 11.5) were included in the study. The factor loadings of the variables were checked by calculating the correlation value of the characteristics of a construct with that construct, whose value was greater than 0.4. The K-R coefficients for the whole instrument and its four subscales (remembering, application, analysis, and comprehension) were 0.8, 0.71, 0.73, 0.87, and 0.89, respectively. Re-testing of the instrument with an interval of two weeks indicated the acceptable stability of the instrument (ICC ≥ 0.8).ConclusionsOur findings showed that the Iranian version of CHLSD is a valid and reliable instrument for measuring the health literacy in patients with diabetes.

Validation of the Iranian version of the ENDOPAIN-4D questionnaire for measurement of painful symptoms of endometriosis

Endometriosis is one of the leading gynecological disorders in reproductive ages. About two-thirds of women with endometriosis experience chronic pelvic pain. There are different methods for the assessment of pain in endometriosis. One of these questionnaires is endometriosis painful symptoms-4 dimensions (ENDOPAIN-4D) questionnaire, which has not been validated in Iran. Therefore, we decided to conduct a study to determine the psychometric properties of this questionnaire. In this study, we randomly selected 169 women with endometriosis from two educational-medical centres of Al-Zahra and Taleghani in Tabriz, Iran, in 2020. We evaluated the validity of ENDOPAIN-4D in terms of face, content, and structure (through exploratory and confirmatory factor analyses). We used internal consistency assessment and test-retest reliability to determine the questionnaire reliability. In this study, the CVI and CVR for the ENDOPAIN-4D instrument were obtained as 0.99 and 0.98, respectively. In the exploratory factor analysis, we extracted a four-factor structure, and the confirmatory factor analysis gave a good fit for the extracted model. We obtained Cronbach's alpha coefficient as 0.96 and the intra-class correlation coefficient (ICC) (at 95% confidence interval) as 0.94 (0.85 to 0.98). The Persian version of ENDOPAIN-4D has acceptable content validity, construct validity and reliability for the evaluation of pelvic pain and gynaecology in Iranian women with endometriosis. Impact Statement What is already known on this subject? There are different methods for the assessment of pain in endometriosis. But there is no specific psychometric instrument to determine the painful symptoms of endometriosis in Iran so far. What do the results of this study add? The Persian version of ENDOPAIN-4D is a valid and reliable instrument for the evaluation of pelvic pain and gynaecology in Iranian women with endometriosis. What are the implications of these findings for clinical practice and/or future research? The validation of the Persian version of the ENDOPAIN-4D questionnaire leads to correct assessment of painful symptoms in Iranian women with endometriosis and will be useful in evaluating the patients' pain intensity and the response to treatment in practice.

Psychometric Properties of Iranian Version of the Cyberchondria Severity Scale (Short-Form of CSS)

Cyberchondria refers to a clinical phenomenon in which repeated Internet searches regarding medical information result in excessive concerns about physical health. Due to the lack of research on the psychometric properties of CCS-12 and the lack of appropriate tools cyberchondria measurement in Iran, this study was conducted to examine the psychometric properties of of the Iranian version of the CSS-12 (short-form). A convenience sample of 420 students (191 men, and 229 females) from Kermanshah University of Medical Sciences were selected to evaluate the psychometric properties of the Cyberchondria Severity Scale (CSS-12). The participants also completed the Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty Scale and Generalized Anxiety Disorder 7-item (GAD-7). LISREL 8 and SPSS-24 were used to analyze data. Cronbach’s alpha, divergent and convergent validity and confirmatory factor analysis were conducted as well. The four-factor structure of CSS-12 (excessiveness, distress, reassurance and compulsion) was supported by the results of Confirmatory Factor Analysis in the Iranian sample. The CSS-12 had positive and significant correlations with health anxiety, intolerance of uncertainty, and GAD-7. Furthermore, the CSS-12 had a negative and significant correlation with the AAQ-II. In general, the four-factor structure of CSS-12 demonstrated acceptable psychometric properties among the Iranian sample. CSS-12 has appropriate psychometric properties for use in research and clinical practice.

Cultural Adaption and Psychometric Analysis of Family APGAR Scale in Iranian Older People.

BackgroundFamily function is a necessary factor that influences older people’s health. The Family APGAR has been widely used to study family functions. However, there has been no Persian version of this instrument to assess family function in older people. The aim of this study was to determine the psychometric properties of the Persian version of the Family APGAR Scale to evaluate the perception of family functions.MethodsThe “forward-backward” procedure was applied to translate the scale from English into Persian. The translated version was checked in terms of validity and reliability, with a sample of 281 older people selected from retirement centers. The factor structure of the scale was also tested using a confirmatory factor analysis. To test reliability, internal consistency and test–retest analyses were performed.ResultsThe results of the confirmatory factor analysis indicated a good structural model. Criterion-related validity was strongly supported by the pattern of association between the APGAR Scale and the social support survey. Cronbach’s α of the scale was 0.88 and test–retest reliability ranged from 0.96 to 0.98, indicating a good range of reliability.ConclusionThe findings of this study suggest that the Iranian version of the Family APGAR is a valid and reliable scale to evaluate family functions in health intervention programs.

The association between dietary behaviors and insomnia among adolescent girls in Iran

BackgroundInsomnia is associated with a poor quality of life and increased risk of somatic and social problems. The aim of current study was to investigate the relationship between dietary behaviors and insomnia in Iranian adolescent girls. MethodsThis cross-sectional study was performed among 988 girls aged 12-18 years. A questionnaire was used to determine dietary behaviors in nine domains. To assess insomnia, a validated Iranian version of the Insomnia Severity Index was applied. Multivariable logistic regression examined the association between dietary behaviors and insomnia in crude and adjusted models. ResultsHighest adherence to regular meal consumption was related to the lowest odds of insomnia (odds ratio [OR]: 0.44, 95% confidence interval [CI]: 0.24-0.81). Compared with individuals who consumed breakfast never or once a week, those who always consumed breakfast had a lower likelihood of insomnia (OR: 0.56, 95% CI: 0.36-0.88). These associations remained significant in all adjusted models. Subjects who ate spicy food every day had 4.73 times greater odds of insomnia than individuals who never ate spicy food (OR: 4.73, 95% CI: 1.09-20.56). After controlling for age, menstruation, parent death, parents’ divorce and parents’ (mother and father) employment status, this relationship remained (OR: 4.59, 95% CI: 1.05-20.10); however, the association was no longer significant after controlling for the other covariates. No significant relationship was found between other dietary habits and insomnia for the unadjusted or adjusted models. ConclusionLowest rates of insomnia were found among participants who had the lowest frequency of eating spicy foods and the highest frequency of eating breakfast and eating regular meals. Further prospective studies are required to confirm these findings.

Associations between Dietary Patterns and Sleep Problems in Adolescent Girls: A Descriptive Cross-Sectional Study

Background: Adolescence may be accompanied by abnormalities in menstrual cycles that result in a higher incidence of sleep problems and related psychological disorders. Dietary factors can intensify or improve sleep problems. This study aimed to evaluate the association between sleep problems and habitual dietary patterns among Iranian adolescent girls. Methods: This study was conducted in cities of Mashhad and Sabzevar, northeastern Iran. A total of 752 adolescent girls aged 12-18 years were recruited from several schools by using a random cluster sampling method. A valid and reliable food frequency questionnaire (FFQ) was used to obtain the dietary intakes of the girls. Validated Iranian versions of the questionnaires were used to assess insomnia and daytime sleepiness prevalences. Results: Three major dietary patterns were identified based on the principal component analysis (PCA), including healthy, western, and traditional dietary patterns. No significant associations were found between the quartiles of healthy (OR: 1; 95% CI 0.62-1.59, P trend = 0.75), western (OR: 1.3; 95% CI 0.8-2.10, Ptrend = 0.16) or traditional (OR: 0.62; 95% CI 0.69-1.82, Ptrend = 0.64) dietary patterns and sleep insomnia. In addition, there were no significant relationships between the quartiles of healthy (OR: 0.85; 95% CI 0.54-1.69, P trend = 0.84), western (OR: 0.81; 95% CI 0.49-1.32, Ptrend = 0.55) or traditional (OR: 1.07; 95% CI 0.66-1.74, Ptrend = 0.9) dietary patterns and daytime sleepiness. Conclusions: No significant association was observed between dietary patterns and insomnia or daytime sleepiness among adolescent girl participants.

Psychometric Properties of the Persian Version of the Personal Meaning Profile in Iran

The Personal Meaning Profile (PMP) is a widely used instrument to measure people's perceptions of personal meaning in their lives. Thisstudy aimed to evaluate the psychometric properties of the Persian version of the PMP. First, the researchers developed the Persian version of this scale using the forward-backward procedure. Then, they examined the face and content validities by both qualitative and quantitative approaches. To evaluate the construct validity, researchers administered the instrument to a sample of 482 medical sciences students and performed exploratory and confirmatory factor analyses. The reliability was assessed using loading factors, Cronbach's alpha coefficients, and composite reliability. An average scale-level of content validity index of the PMP with 57 items was 0.80. The findings revealed that the Persian version of the PMP comprises five factors explaining 50.57% of the total variance. The confirmatory factor analysis indices showed a moderate fit for the data. Reliability of the Iranian version of PMP was demonstrated with a Cronbach's alpha of 0.893. Consistency was established with test-retest reliability with an interval of 2weeks (Intracluster Correlation Coefficient = 0.983, p < 0.001). Moreover, the criterion validity demonstrated a significant inverse relationship between the PMP and General Health Questionnaire (r = - 0.34, p < 0.001). This study indicated that the Persian version of the PMP is an acceptable, reliable, and valid measurement to evaluate the meaning in life in Iranian medical sciences students.

Investigation of the psychometric properties of children's somatization inventory in Iranian adolescents.

BACKGROUND:This study aimed to investigate the psychometric properties of children's somatization inventory (CSI-24) in a sample of Iranian school adolescents.MATERIALS AND METHODS:In this study, after translating and back-translating CSI-24, comparisons were made with the original version. The study population consisted of 394 school adolescents. Cronbach's alpha method was used to examine the reliability of the scale. Furthermore, the correlation of the scale with the Symptom Checklist-90-Revised was evaluated to determine its criterion validity, using Pearson's correlation coefficient. Exploratory and confirmatory factor analysis methods were applied for construct validity.RESULTS:Investigation of the psychometric properties of the Iranian version of CSI-24 showed its high reliability and confirmatory factor analysis results show the model's satisfactory fitting.CONCLUSION:The Persian version of CSI-24 is a useful self-report tool for evaluating the physical complaints of Iranian school adolescents aged between 12 and 18 years.

Validity and reliability: The psychometric properties of the Persian version of Short Form of the Impulsiveness Questionnaire UPPS-P in Iran

BACKGROUND:Impulsiveness is a multidimensional and multifaceted construct that plays an important role in understanding various psychopathology and problematic behavior. It is necessary to study the psychometric properties of instruments in the new culture before its scientific application, and it also contributes to external validity. The current study was conducted to determine the psychometric properties of the Persian version of Short Form of the Impulsiveness Questionnaire UPPS-P (SUPPS-P) in a sample of male soldiers serving in the military service.MATERIALS AND METHODS:The present research design is cross-sectional in 2019–2020. The Iranian version of the SUPPS-P was prepared across forwarding translation, reconciliation, and back-translation. The research sample included 254 soldiers who were selected via convenience sampling method and completed a set of scales, including the SUPPS-P scales, short-form self-compassion scale, McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Cognitive Flexibility Inventory (CFI), Perth Alexithymia Questionnaire (PAQ), and the Deliberate Self-harm Inventory (DSHI). The construct validity of SUPPS-P scale was measured using confirmatory factor analysis and convergent and divergent validity. For reliability, Cronbach's alpha and test–retest reliability (with 2 weeks interval) were used. Data were analyzed using LISREL software (version 8.8) and SPSS version 22.RESULTS:The results showed that the SUPPS-P scale is a reliable and valid scale with acceptable internal consistency and acceptable test–retest reliability among soldiers. In terms of convergent validity, SUPPS-P showed a significant positive correlation with measures of MSI-BPD, PERS, and DSHI. SUPPS-P showed a negative correlation with self-compassion and cognitive flexibility, thus demonstrated a good divergent validity. The results of this study also provide support for the five-factor model of the SUPPS-P scale.CONCLUSION:The SUPPS-P instrument showed acceptable validity and reliability and could be useful in assessing impulsivity in Iranian society. The SUPPS-P scale shows notable promise as a measure for use in impulsivity research and clinical settings.
