The pretest-posttest control group design is one of the most widely used quantitative experimental design models for evaluating the efficacy of programs, treatments, and interventions. Despite the prevalence and utility of this research design, best practices for data analytical procedures are not clearly defined. Invalid results decrease the chance of generalization. Given that Iranian Journals are interested in publishing pretestposttest control group design studies, it is important to denote the accuracy of them. The aim of the current study is to explore the correct procedure for using ANCOVA in pretest-posttest control group designs to mitigate the potential limitations of this approach. This study explores the use of ANCOVA in pretest-posttest control group design. It has been done by analyzing data from experimental studies published in five Iranian journals indexed in PubMed or Scopus between 2011 and 2018. The results indicate that among the 280 published experimental studies in these journals, 53 papers (18.9 percent) used ANCOVA as the statistical test in pretest-posttest studies. The power of the test represents the probability of detecting differences between the groups being compared when such differences exist. Our analysis concludes that ANCOVA, which runs a multiple linear regression, is a suitable method for comparing and examining pretest-posttest study designs. Implications of this study have potential utility for researchers employing the use of pretest-posttest control group designs in various fields in and outside of Iran. [ABSTRACT FROM AUTHOR]

When people hear about someone who has cancer, it is not uncommon for them to experience feelings of sympathy and pity. However, while these reactions are well-intentioned, they can have negative consequences for the patient. Sympathy is a feeling or emotional response characterized by compassion, understanding, and concern for the suffering or hardship experienced by another person. It involves the ability to share in the feelings of others and to genuinely care about their well-being. This article will explore the negative consequences of sympathy and pity reactions of people toward cancer patients. [ABSTRACT FROM AUTHOR]

Objective: Limited research has examined the psychometric properties of death depression scales in Persian populations with cardiac disease despite the need for valid assessment tools for evaluating depressive symptoms in patients with life-limiting chronic conditions. The present study aimed at evaluating the reliability and validity of the Persian Version of Death Depression Scale - Revised (DDS-R) in Iranian patients who had recent acute myocardial infarction (AMI). Method: This psychometric study was conducted with a convenience sample of 407 patients with AMI diagnosis who completed the Persian version of the DDS-R. The face, content, and construct validity of the scale were ascertained. Internal consistency, test-retest, and construct reliability (CR) were used to assess reliability of the Persian Version of DDS-R. Results: Based on maximum likelihood exploratory factor analysis and consideration of conceptual meaning, a 4-factor solution was identified, explaining 75.89% of the total variance. Goodness-of-fit indices (GFI), Comparative Fit Index (CFI), Normed Fit Index (NfI), Incremental Fit Index (IFI), and Root Mean Square Error of Approximation (RMSEA) in the final DDS-R structure demonstrated the adequacy of the 4-domain structure. The internal consistency, construct reliability, and Intra-class Correlation Coefficients (ICC) were greater than .70. Conclusion: The DDS-R was found to be a valid and reliable assessment tool for evaluating death depression symptoms in Iranian patients with AMI. [ABSTRACT FROM AUTHOR]

Objective: This research aimed to study the effect of life skill training on mental health of Iranian middle school students. Method: This experimental study was conducted In 2015 on 100 students of city of Ghaemshahr (North of Iran), who were randomly selected and divided into two equal groups of intervention (n = 50) and control (n = 50). Qualified trainers provided eight sessions (two sessions a week for 2 hours) of life skills training to the intervention group for one month. The control group did not participate in any training sessions during the same period. Mental health in both groups was assessed by a questionnaire pre- and post-training. Data were analyzed using descriptive and infernal (ANCOVA and paired t-test) statistic tests. Results: The average age of the participants in both groups was 13.5±1.01. ANCOVA test results revealed that the average score of violence, addiction, stress and sensation-seeking before and after the training was statistically significant in the intervention group and control groups (p<0.001). Conclusion: Life skills training had positive effects on mental health of the participants. Given the importance of mental health in modern societies, it is necessary for schools to incorporate life skills in their curriculum to support the mental health of adolescents.
