3.2 Descriptive Statistics
The median age of the sample was 32 years. Fifty-nine per cent of the sample was male. Only 1.5% of the sample disengaged prior to assessment.
The data was assessed for normality. Due to a violation of the assumptions of normality, CRT, DUP, SANS and CDSS scores were log10 transformed. Following retesting, the transformed variables were normally distributed and met criteria for parametric statistics. The CRT did not meet assumptions of normality, even following transformation and was therefore recoded into a binary dummy variable. These transformed variables were used in all parametric testing. Age was recoded into six age bands as follows: 18-28, 29-38, 39-48, 49-58, 59-68, 69-78.
Descriptive statistics are reported in Table 1. A breakdown of the TALE by presence, median age of exposure, and child versus adult exposure is reported in Table 2.
A series of independent samples t-tests and chi square tests were conducted to investigate sex differences. A small significant difference in SAPS scores between males > females was found (Cohen’s d = .38). A moderate significant difference in CDSS scores between males > females found (Cohen’s d = .5). Males had a small increased likelihood of substance use compared to females (Phi = -.21).
