Background and aims: Some people are preoccupied with their sexual urges and fantasies and lose control over their sexual behaviors, which can cause adverse consequences for their health and wellbeing. One of the options available for individuals seeking treatment for compulsive sexual behavior disorder (CSBD) is a self-help group based on the twelve-step program. The main purpose of the current study was to examine the direct and indirect (through meaning in life and hope) relationships between involvement in Sexaholics Anonymous (SA) and life satisfaction. Methods: The sample consisted of 80 Polish members of SA (72 men and 8 women) with a mean age of 38.96 years (SD 5 10.56). The Sex Addiction Screening Test-Revised, the Meaning of Life Questionnaire, the Herth Hope Index, the Satisfaction with Life Scale, and items adapted from the Alcoholics Anonymous Involvement Scale were used to measure the study variables. Results: Path analysis showed a direct positive relationship between SA involvement and life satisfaction. Moreover, the relationship between these variables was mediated by the presence of meaning in life and hope. Simultaneously, more severe symptoms of CSBD were related to lower levels of the presence of meaning in life and higher levels of the search for meaning in life, which, in turn, predicted lower levels of life satisfaction. Discussion and conclusions: The results suggest that finding meaning in life and restoring hope partly underlie the relationship between SA involvement and life satisfaction.  Kulcsszavak: compulsive sexual behavior disorder, life satisfaction, twelve-step program, self-help groups, meaning in life, hope
