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).
