Practitioner Development

The social impact of assertiveness. Research findings and clinical implications.

Delamater et al. (1986) · Behavior modification 1986
★ The Verdict

Assertiveness training needs empathy and context tweaks so clients stay skilled and liked.

✓ Read this if BCBAs coaching teens or adults on social skills in clinic, school, or day-program settings.
✗ Skip if Clinicians focused only on early-childhood mand training or severe problem behavior.

01Research in Context

01

What this study did

Delamater et al. (1986) pulled together every study they could find on assertiveness.

They asked one question: how do people feel about someone who acts assertive?

The review looked at lab studies, therapy notes, and real-world chats.

02

What they found

Assertive people are seen as skilled, but not always liked.

Sex, empathy, and the setting change how the behavior lands.

In short, competence and likability often pull in opposite directions.

03

How this fits with other research

Green et al. (1984) seems to disagree. Their female models got higher likability scores when they spoke up.

The twist: those models gave praise, not refusals. Positive assertiveness feels different.

Osnes et al. (1986) and White (1986) back the main point. Adding small talk or empathy keeps the skill while saving face.

Rosen (1987) shows the fix works in real life. Disabled college students gained assertive moves after a short BST course.

04

Why it matters

You can teach the skill, but you must also teach the wrapper.

Have clients rehearse the words, then add a friendly comment or brief empathy line.

Pick role-play scenes that match their daily life—praise at work, calm refusal at home.

This keeps the new behavior from backfiring and boosts the odds it sticks.

03Original abstract

Recent studies on the social impact of assertiveness have revealed that although assertiveness is perceived as a dimension that is regarded as highly competent and skillful, it also is viewed as unfavorable interpersonal behavior. Such factors as sex, empathy, assertiveness level, and race appear to moderate the perceptions of assertiveness, attesting to the highly complex, situationally specific nature of assertiveness and its social impact. Various findings about these moderators have been reported, but conclusive generalizations regarding this new area must await the results of future studies. Finally, several clinical implications for assertiveness training are explored.
