Learning Outcomes

• Identify their preference for one of 4 personal influence styles: Passive, Assertive, Openly Aggressive, or Passively Aggressive

• Learn why assertive behaviour is the one style that always yields positive results

• Understand how other influence styles can hamper interpersonal communication

• Discover the behavioural cues that signal each style


The III was developed to help individuals assess their interpersonal influence style. The model upon which the inventory statements are based is an assertive behaviour model. This model suggests that 2 sets of behaviours create 4 behavioural mixes. One set of behaviour is related to an individual’s degree of openness or candor. Another set of behaviours is related to an individual’s degree of consideration for another or others.

When an individual employs these two sets of behaviours in varying proportions, an influence style is created. Depending on the relative use of each set of behaviours, 1of 4 influence patterns results.

How It Works

Presented with 40 statements, individuals choose 1 of 5 responses that they feel is most characteristic of their behaviour, as they perceive it. Each set of statements measures influence style by focusing on the 4 indicators: thoughts, emotions, nonverbal behaviour, and verbal behaviour.

Uses for the III

The III is a useful instrument for many training purposes. Use it as a stand-alone instrument or as part of a larger training initiative. It’s also helpful as an objective, non-threatening means of diagnosing interpersonal tensions within groups. Other appropriate uses include:

Negotiation: The III can show negotiators the attitudes and behaviors they take to the negotiating session and enlighten them as to how assertive styles of influence can produce win-win results.

Leadership Skills Training: The III can help managers discover how they influence others and how assertive styles of influence can elicit more positive reactions to their visions and engender more productive and satisfied workers.

Communication Skills Training: The III can help workers at all levels become aware of how they communicate with others. It can also show them how assertive behavior will help get their messages across clearly and directly and improve communication flow in general.

Conflict Resolution: The III is useful in making individuals aware of how they handle conflict and in helping them to learn that conflict can be constructive if it is openly and clearly expressed.
