This study investigated the extent and types of altered beliefs, attitudes, and values of 53 subjects who reported having had a neardeath experience (NDE). A control group was composed of 27 individuals who reported having had similar life-threatening incidents but without a corresponding NDE. In addition, 45 significant others in the lives of the participants in these groups rated the extent and types of changes as a means of obtaining outside corroboration regarding the changes. The results indicated that the NDE group went through a significantly greater number of changes than persons who went through similar life-threatening situations but without having had a corresponding NDE. In addition, the extent and types of changes were mostly corroborated by significant others. Specific areas of change included increased concern for others, reduced death anxiety with a strengthened belief in an afterlife, increased transcendental experience, reduced interest in material possessions, increased self-worth, increased appreciation for natural phenomenon, and an enhanced awareness of paranormal phenomenon. Analysis of the depth of the experience indicated that the depth and the extent of change were positively correlated. Collectively, this information strongly suggests that it is the actual NDE itself, rather than some other factor such as merely being exposed to a life-threatening situation, that is crucial in facilitating change.

The Self-Appraisal Questionnaire (SAQ) is a 72-item self-report measure designed to predict violent and nonviolent recidivism among adult criminal offenders. The results from using samples from Australia, Canada, England, Singapore, and two samples from the United States (North Carolina and Pennsylvania) indicated that (a) the SAQ has sound psychometric properties, with acceptable reliability and concurrent validity for assessing recidivism and institutional adjustment; (b) there were no significant differences among the scores of the White, African American, Hispanic, and Aboriginal Australian offenders on the SAQ; (c) there were no significant differences among offenders who completed the SAQ for research purposes versus offenders who completed it as part of a decision-making process. Results provided support for the validity of the SAQ to be used with the culturally diverse offenders involved in this research and provided further evidence that contradicts concerns that the SAQ as a self-report measure may be susceptible to lying, and self-presentation biases.

Toch (1977) developed the 56-item Prison Preference Inventory (PPI) to measure inmates' preferences regarding eight psychosocial aspects of the prison environment. Items on the PPI consist of statements that are supposedly indicative of preferences for one of these eight aspects paired with statements that are indicative of one of the other seven aspects, and respondents indicate their preference. Evidence of construct validity is limited, and no studies have examined substantive validity, that is, whether each statement is reliably indicative of the intended environmental aspect and of only that aspect. The current study examined the substantive validity of the items with Australian prisoners and found that for 21 (37.5%) of the 56 items either or both statements in the pair failed to demonstrate adequate validity. When the more stringent criterion of displaying substantive validity for each of four demographic subgroups was applied, only 8 of the 56 items were deemed valid.
