The aim of this study is to develop an instrument to measure individuals’ sense of belonging to a family. A five-point Likert-type scale consisting of 17 items, which represents the sense of belonging to a family, was obtained. The scale was administered to 1579 university students from different universities in Konya. Before the principal component analysis, Kaiser-Meyer-Olkin (KMO) and Bartlett’s tests were performed to assess the suitability of the data for factor analysis. As a result of these tests, the KMO value was found to be.96 and Bartlett’s test for sphericity value was found to be significant at 16943.875 (p <.001). As a result of the factor analysis and varimax rotation, it was determined that the scale had a two-factor structure (family belonging and self-belonging) explaining 60% of the total variance. The internal consistency coefficient (Cronbach’s alpha) of the scale was calculated as.94. The data were then recollected, and confirmatory factor analysis was performed on the data from 1500 individuals. Confirmatory factor analysis determined that the tool, entitled the Family Belonging Scale (FBS), produced expected values and is a valid and reliable tool that can be used in all kinds of services concerning for families, especially in family counseling.
