There are not many studies about affirmative competence and practices among mental health professionals working with lesbian, gay, and/or bisexual (LGB) clients.

The objectives of this research are to assess the levels of affirmative competence and practices of professionals in Ibero-American countries.

We aim to compare differences regarding gender, country of origin, religious beliefs, political orientation, sexual orientation, age, education, marital status, and possessing specific training related to working with LGB clients, in order to determine the predictive association of the variables under study.

The sample consists of 630 therapists from various countries various Ibero-American countries: 23% from Portugal, 23.2% from Brazil, 19.1% from Spain, 6.7% from Mexico, 6.7% from Argentina and 18.6% from other countries. Ages ranged from 19 to 75 years old, with a mean age of 41.46years. The socio-demographic questionnaire, the Sexual Orientation Counselor Competency Scale, and the Affirmative Practice Questionnaire were the measures used.

The results show statistically significant differences when comparing marital status, sexual orientation, political orientation, religious beliefs, level of education, and specific training concerning LGB issues. Age, gender, and country of residence show no statistically significant differences. The linear regression model demonstrates that there is a significant predictive value between affirmative competence and practices with LGB clients.

This study indicates that mental health professionals should undergo some type of academic or professional training and/or possess experience in regards to working with LGB clients, in order to enhance their approach when working with this population.
