ABSTRACT
Objectives:
FAP Intimacy Scale (FAPIS) is a self-reported measure allowing to assess the process of change in a client’s intimate relating, specific to behavioral definition of intimacy. FAPIS consists of 14 questions with three subscales: Hidden Thoughts and Feelings, Expression of Positive Feelings, and Honesty and Genuineness. The aim of this study is to assess psychometric properties of the Polish version of this tool.
Methods:
A total of 423 people (350 women and 70 men, others did not reveal gender) in the age of 18–55 completed online the set of self-reported measures. Confirmatory factor analysis and bivariate Pearson correlations were calculated.
Results:
The three-factor internal structure of the tool was confirmed. All three scales of the instrument demonstrated very high internal consistency. The theoretical validity of the tool has been confirmed: the scales are significantly correlated with each other and with the overall score. FAPIS scales were associated with other measures of various aspects of intimacy or emotions experienced in relationships (e.g., anxiety, avoidance, closeness), as well as depression, and various aspects of interpersonal competence.
Conclusions:
The Polish version of the FAPIS presents itself as a valuable tool for use in scientific research and therapeutic practice.
