Are Scientific Research Programmes Applicable to Theology? On Philip Hefner’s Use of Lakatos

This paper focuses on the work of Philip Hefner, who employs Lakatosian scientific research programme methodology in order to develop and articulate certain theological concepts. Lakatos’ methodology has been criticised on several counts, including its dependence on reconstructed history and the risk of prematurely abandoning a scientific theory. Hefner does not address these critiques directly, nor does he modify his own methodology sufficiently to avoid valid criticism. Finally, this paper explores the implications of applying a Lakatosian methodology to theology for the way in which we understand truth in relation to the methodology’s criterion of fruitfulness.     

Confirmatory Factor Analysis of the Structure of Adult ADHD Symptoms

Previous research has examined the factor structure of ADHD symptoms in adults using confirmatory factor analysis and there is mixed support for two-factor, three-factor, or more complex bifactor models. The current study re-examines these factor structures on the basis of not only overall model fit, but also criteria such as chi-square difference tests, invariance, reliability, and validity. Three datasets were pooled to form a total sample of 430 adults (50% female). Participants completed questionnaires assessing their ADHD symptoms, education, psychopathology, and parenting (the latter as validity variables). Although the bifactor models demonstrated the best fit, the reliability and construct replicability of specific factors in these models was poor. The three-factor model had good fit and demonstrated good reliability, validity, construct replicability, and some invariance across gender and dataset. Our results replicate previous studies that find superior fit for bifactor models. However, the superior statistical fit may reflect only the increased complexity of these models. The more parsimonious three-factor model may demonstrate stronger validity and clinical utility.     

Social Support,Economic Hardship and Psychological Distress in Spanish and Portuguese At-Risk Families

Individuals with low socioeconomic status generally have worse mental health outcomes than their wealthier counterparts; a tendency that is exacerbated during financial crises. However, social support might buffer the effects of stress on mental health. In this study, we tested whether social support mitigated the effects of economic hardship on psychological distress on an at-risk sample from two of the European countries most affected by the 2008 economic downturn: Spain and Portugal. Participants were 249 caregivers enrolled in Child Welfare Services (73.0% women). Results showed that economic hardship and a negative indicator of social support (network dysfunctionality) were significant predictors of belonging to the psychological distress clinical group (OR: 2.35 and 1.80, respectively). However, no significant interaction effects were observed, thereby refuting the buffering effect hypothesis. When we conducted an in depth analysis of the clinical group, a significant moderation effect emerged. Our results suggest that, for at-risk populations, the detrimental effects of dysfunctional networks on mental health can outweigh the benefits of positive assistance and that social support is a potential stress buffer only for individuals in the clinical spectrum. These findings indicate that the protective effect of social support during circumstances of intense economic adversity is limited.
