4. Mayes and Ganster (1983) conducted an MTMM analysis of two methods of measuring four psychological needs:
• Two methods the Manifest Needs Questionnaire (MNQ) and the Personality Research Form (PRF) a. content validity b. convergent validity c. discriminant validity d. predictive validity
• Each method included scales measuring four different psychological needsachievement, autonomy, affiliation, and power (i.e., these are hypothesized to be relatively independent needs).

15 Sarah develops a new measure of Schizoid Personality Disorder, and she examines its validity (as a measure of Schizoid PD). She administers her new measure to a sample of participants. In addition, she also asks the participants to complete existing measures of six other personality disorders (Histrionic, Borderline, etc., see below).
Based on her understanding of Schizoid PD and the other PDs, she generates a set of “predicted corrections”. She believes that, if scores on her new measure are indeed validly interpretable in terms of Schizoid PD, then her new scale will be correlated with scores on the Histrionic PD measure at r= .60, correlated with scores on the Borderline PD measure at r = .30, etc. The table below presents the six predicted correlations.
