In a descriptive and validation study, 172 and 228 students from Birjand University were selected through multi-stage random sampling method and completed the Basic Need Satisfaction in Relationships Scale (La Guardia et al. 2000), Life Satisfaction Test (Diener et al. 1985), The Social and Emotional Loneliness Scale for Adults (Ditommaso et al. 2004), and Depression, Anxiety, Stress Scale (Lovibond, & Lovibond, 1995). Internal consistency, exploratory and confirmatory factor analysis, convergent and constructive validity was evaluated using SPSS.16 and AMOS.24 software. The results showed that the scale had three-factor structure with the variance explained 70.92%. The second-order confirmatory factor analysis confirmed. The scale had good construction reliability. The convergent validity confirmed in relation to life satisfaction and its divergent validity in relation to the social loneliness and depression (P≤0.01). There was no significant difference based on age, gender and marital status (P>0.05).
