This study classified adult men’s attitudes toward professional help-seeking using cluster analysis and examined group differences among the identified subtypes. A total of 292 men completed a semantic differential scale, and four clusters were identified: ambivalent, unformed attitude, positive, and negative. One-way ANOVA and chi-square tests revealed differences in help-seeking intention, psychological distress, and gender role conflict. The positive group reported the highest help-seeking intention, counseling experience, and consideration of seeking help, with the lowest distress and conflict. The ambivalent and negative groups both showed elevated distress and conflict, but the ambivalent group reported higher help-seeking intention, anxiety, and stronger male superiority beliefs. The unformed group showed generally low levels across all variables. These findings highlight the value of identifying attitudinal subtypes to promote counseling service use among men. This study contributes by identifying the negative group—previously unaddressed—and clarifying the characteristics of the ambivalent group. Limitations and directions for future research are discussed.
