[Validity and reliability of Social Support Interactions Scale SSL12-I in a population of elderly people in Poland]

This study aimed at assessing validity and reliability of Social Support Interactions Scale and it's usefulness in evaluation of social support received by elderly people in Poland. Theoretical validity of the scale was evaluated using exploratory factor analysis (principal components method) and confirmatory factor analysis. Reliability was calculated by Cronbach's alpha index and evaluating its internal consistency. Analyses showed some faults in theoretical validity of subscales concerning different dimensions of social support, which decrease their reliability. Nevertheless, scales constituting this survey mostly fulfill Kline's and Nunnaly's criteria, which means that they have acceptable internal consistency. Results confirm acceptable value of Social Support List - Interactions Scale for evaluation of social support received by elderly people in Polish conditions
