| Description | The Problem Solving Index (PS Index; Greer, 1961) was developed as part of a study investigating the relationship between squad leader indulgence and group effectiveness in Army infantry rifle squads and Air Force crews. The index consists of 5 items to measure how much a respondent perceives their squad leader as helpful or as a problem solver. Each item is responded to in five-step intervals, and the score is the sum of the five items; a high rating indicates a high perception of the leader as a problem solver. |
