UCLA Multidimensional Condom Attitudes Scale [UMCAS-25]

Description

The UCLA Multidimensional Condom Attitudes Scale (UMCAS-25 / MCAS) is a 25-item psychometric instrument developed by Helweg-Larsen and Collins to assess multiple dimensions of individuals’ attitudes toward condom use. It was designed on the premise that condom-related attitudes are multidimensional rather than adequately represented by a single overall score.

Purpose

The scale evaluates beliefs and attitudes that may influence condom acceptance, intention to use condoms, and actual condom-use behavior. It can therefore be used in research on sexual health, HIV/STI prevention, contraceptive behavior, and safer-sex practices.

Dimensions

The UMCAS-25 includes five distinct dimensions:

• Reliability and Effectiveness
• Pleasure associated with condom use
• Identity Stigma
• Embarrassment about Negotiation and Use
• Embarrassment about Purchase

Scoring

The original scale uses a 7-point Likert-type response format, ranging from strong disagreement to strong agreement. Some negatively worded items require reverse scoring. Scores are calculated separately for each subscale, with higher scores reflecting more positive condom-related attitudes.

Because of its multidimensional structure, the developers recommend not combining all items into a single global score.

Research Applications

The UMCAS-25 is useful in studies examining sexual attitudes, condom-use intentions, safer-sex behaviors, sexual health education, and STI/HIV prevention interventions. It has also been applied across different cultural and population groups.
