    Global positioning system technology (GPS) for psychological research: A test of convergent and nomological validity
    (Frontiers Media, 2013) Wolf, P; Figueredo, A J; Jacobs, W J
    The purpose of this paper is to examine the convergent and nomological validity of a GPS-based measure of daily activity, operationalized as Number of Places Visited (NPV). Relations among the GPS-based measure and two self-report measures of NPV, as well as relations among NPV and two factors made up of self-reported individual differences were examined. The first factor was composed of variables related to an Active Lifestyle (AL) (e.g., positive affect, extraversion…) and the second factor was composed of variables related to a Sedentary Lifestyle (SL) (e.g., depression, neuroticism…). NPV was measured over 4 days. This timeframe was made up of two week and two weekend days. A bi-variate analysis established one level of convergent validity and a Split-Plot GLM examined convergent validity, nomological validity, and alternative hypotheses related to constraints on activity throughout the week simultaneously. The first analysis revealed significant correlations among NPV measures- weekday, weekend, and the entire 4-day time period, supporting the convergent validity of the Diary-, Google Maps-, and GPS-NPV measures. Results from the second analysis, indicating non-significant mean differences in NPV regardless of method, also support this conclusion. We also found that AL is a statistically significant predictor of NPV no matter how NPV was measured. We did not find a statically significant relation among NPV and SL. These results permit us to infer that the GPS-based NPV measure has convergent and nomological validity.

    The Psychometric assessment of human life history strategy: a Meta- analytic construct validation
    (American Psychological Association, 2014) Figueredo, A J; Wolf, P; Olderbak, S; Gladden, P; Fernandes, H; Wenner, C; Hill, D; Andrzejczak, D; Sisco, M; Jacobs, W; Hohman, Z; Sefcek, J; Kruger, J; Howrigan, D P
    A growing body of empirical literature supports the validity of psychometric assess ments of human life history strategies, but no comprehensive quantitative summaries have yet been published. We present a psychometric validation study of a 20-item Short-Form of the Arizona Life History Battery (ALHB), the Mini-K, using meta-analytic procedures to survey a multiplicity of published and unpublished studies on English-speaking North American college student samples. Correlations between the Mini-K with other measures of related constructs describe the dimensions of the broader conceptual framework encompassed by human life history strategy and em- pirically establish a nomological network surrounding the Mini-K by quantitatively characterizing its system of relations to related and unrelated constructs. These con- structs include the General Factor of Personality, Mutualistic and Antagonistic Social Strategies, Emotional Intelligence, Executive Functions, Covitality, and Evaluative Self-Assessment as well as other indicators of human life history strategy, including all those comprising the ALHB and many others not used in the ALHB, and indicators of one’s Romantic Partner’s life history strategy. Although a single measure cannot capture something as complex and multifaceted as life history strategy, both the Mini-K and the ALHB of which it is a part, perform as predicted by evolutionary psychological theory within this wider conceptual framework.
