Investigating psychometric characteristics of the brief family relationship scale and its correlation with suicide in high school students

Family relationship and parent-child relations is a main factor in development and socialization of children. Distressed and disrupted relationship put people into suicide. The aim of this research was to investigate validity, reliability and Confirmatory factor analysis of “The Relationship dimension of the Family Environment Scale (FES)”, and its correlation with suicide in students. The study method was descriptive in the form of correlation. Statistical community included of all high school students in Ardabil city (12387 students) that 400 students based on Cochran's Sample Size Formula have been chosen as sample by available sampling. The research instrument was The Brief Family Relationship Scale (moos & moos) and Suicidal Behavior Questionnaire-Revised (Osman et al.). For analyzing data, Pearson correlation coefficient, Cronbach`s alpha coefficient and Confirmatory factor analysis were used. Cronbach`s alpha coefficient for total scale and subscales (Cohesion, Expressiveness and Conflict) was in turn 0/81, 0/77, 0/78, 0/77. There was a significant Correlation between The Brief Family Relationship Scale (p˂0/01, r=-0/32) and cohesion (p˂0/01, r=-0/30), Expressiveness (p˂0/05, r=-0/10) and Conflict (p˂0/01, r=0/26) subscales with suicide. Confirmatory factor analysis showed that this questionnaire has a good fitness (CFI=0/96, RMSEA= 0/056, RMR= 0/041, NFI=0/93). In regard to this results, we can conclude that this questionnaire has acceptable validity and reliability in Ardabil society.
