A tool with appropriate reliability and validity is needed to measure the behavioral inflexibility of different age groups of children with autism disorder.there is a research gap due to disagreement on the relationship between behavioral inflexibility and age. So, the question is whether the factor structure of the Lecavalier Behavioral Inflexibility Scale is invariant. In different age groups.
Aims: The present study aimed to investigate the validity and invariance of the factor structure of the Lecavalier Behavioral Inflexibility Scale in children with autism disorder aged 3-6 and 7-12 in Isfahan.
Methods: The research method was descriptive-survey and applied in terms of purpose. The statistical population was children with autism disorder aged 3-12 in Isfahan, of whom 450 children were randomly selected, and the data obtained from 430 of them (230 for exploratory factor analysis and 200 for confirmatory factor analysis) were analyzed. The GARS Autism Symptoms Diagnostic Scale (GARS) (2012) with Cronbach’s alpha of 0.89 and the Lecavalier Behavioral Inflexibility Scale (BIS) (2020) with Cronbach’s alpha of 0.97 were used.
Results: Data were analyzed by Cronbach’s alpha, exploratory and confirmatory factor analyses. The Behavioral Inflexibility Scale (CVR> 0.62 and CVI> 0.79) had acceptable internal consistency in the two age groups (α> 0.70). ∆x2 of the restricted and unrestricted models of the measurement residues were equal in different age groups [∆x2 (90)= 108.51, p= 0.089].
Conclusion: The Persian version of the Lecavalier Behavioral Inflexibility Scale has acceptable validity and reliability for both age groups, and its factor structure is invariant.

The existence of meaning in life of the elderly is an important factor for the continuation of their life and finding meaning in life serve an important role in mental health and quality of life of the elderly. Therefore, this research aimed to investigate the effectiveness of logotherapy on depression and positive psychological characteristics of the elderly living in Isfahan. The research method was semi-experimental with pretest-posttest and follow-up design with a control group. The participants included all the elderly aged above 60 years old living in Isfahan. First, two centers were selected among Retired Teachers Associations and then, 40 participants were selected purposefully based on inclusion and exclusion criteria and were randomly assigned with an equal ratio into the experimental and control groups (20 participants each). The experiment group were exposed to the Logotherapy for 11 90-minute sessions, while control group did not receive any intervention at this time. Measurs consisted of Yasavage et. al's elderly depression scale and Rashid's positive psychological characteristics scale. Utilized to analyze of the data was SPSS-23 software. Analysis of Covariance (ANCOVA) demonstrated that logotherapy has a significant role in improving depression and positive psychological characteristics of the elderly (P<0.05). According to the findings of the current research, logotherapy can be used as an efficient method at counselling and psychotherapy centers in order to creat good feeling in the elderly, in turn leading to the decrease of their inanity feeling and depression.
