Why are some of us more inclined than others to stick up for ourselves, not aggressively, but assertively. Assertive people let others know when they feel mistreated and they’re confident saying “no” to unwanted demands.
Presumably it has to do with how see ourselves, yet past research has established that two key aspects of the self-concept – good feelings about the self (“self-liking” or “self-confidence”) and seeing oneself as competent – are not strongly related to assertive behaviour.
Daniela Renger, a researcher at the Institute of Psychology at Kiel University in Germany, believes this is because most relevant to assertiveness is self-respect – “a person’s conviction that they possess the universal dignity of persons and basic moral human rights and equality”. Across three studies published in Self and Identity, Renger shows that self-respect is a distinct psychological concept and that it is uniquely correlated with assertive behaviour.
For her studies, Renger devised a new, four-item self-report measure of self-respect. Participants rated their strength of agreement with:
In everyday life I always see myself as a person with equal rights
I always see myself as a person of equal worth compared with other people in my life
I am always aware that I have the same dignity as all other human beings
If I look at myself, I see a person who is equally worthy compared with others
In an initial study, 343 women and men in Germany (average age 33) completed this measure, plus questionnaires tapping their self-competence (e.g. “I am almost always able to accomplish what I try for”) and self-confidence (e.g. “I look at myself with warmth and affection”; “It is always worth taking good care of myself”). They also completed an 8-item measure of assertiveness, for example saying whether they would feel comfortable “telling a companion you don’t like a certain way he or she has been treating you”. Nearly a hundred of the participants completed these same questionnaires again nine months later.
Based on her analysis of the participants’ answers to the various measures, including the correlations within and between them, Renger concluded that self-competence, self-confidence and self-respect are distinct aspects of the self-concept. Also, while all three factors correlated with assertiveness, only self-respect had a unique association with assertiveness when accounting for the other two factors. Finally, there was some tentative causal evidence: having greater self-respect at Time 1 correlated with increased assertiveness as measured 9 months later, but the reverse was not true (having greater assertiveness initially was not associated with increased self-respect).
