PROBLEM: This paper examines the effect of one form of chronic stress--household crowding--on psychological well-being, as measured by multiple inverse indicators of psychological well-being. We rely on data from a large (n = 2017) random sample of households in Bangkok, Thailand, a context that has a higher level and broader range of crowding than typically found in the United States. Objective household crowding is found to be detrimental to psychological well-being, controlling for a number of background characteristics. The effect of objective crowding is mediated by subjective crowding, which has strong, consistent and direct detrimental effects on well-being. There is no evidence of a gender effect. Extended family households are not uncommon in Bangkok, but the effects of objective and subjective crowding are similar in both two- and three-generation households, as well as in one- and multiple-couple households. The argument that subjective crowding is an effect, rather than a cause, of psychological well-being is examined and rejected. The findings suggest that crowding, as a chronic source of stress, constitutes a major threat to psychological well-being. Although the empirical analyses are based on data from one city, we frame the issue of household crowding in a historical and theoretical context in order to suggest in which cultural settings household crowding is most likely to have detrimental effects on psychological well-being.

SOLUTION: Chronic stress and psychological well-being: evidence from Thailand on household crowding.

PROBLEM: Previous studies with undergraduates have provided support for the reliability and oblique three-factor structure of a new scale, the Pain Catastrophizing Scale (PCS). We examined the reliability and validity of the PCS in adult community and pain outpatient samples. The PCS showed a high internal consistency in both groups. Using data from the community sample, confirmatory factor analyses showed that the PCS taps a single construct characterized by three related dimensions. Gender differences were obtained on the PCS total score in the community and the outpatient samples. The analyses also showed significant differences between the community and the outpatient samples on the PCS total and subscales. Overall, the results showed strong evidence of criterion-related, concurrent, and discriminant validity for the PCS in the community sample. Limitations of the present study are discussed.

SOLUTION: The Pain Catastrophizing Scale: Further Psychometric Evaluation with Adult Samples

PROBLEM: The fatal adult motor neuron disease amyotrophic lateral sclerosis (ALS) shares some clinical and pathological overlap with frontotemporal dementia (FTD), an early-onset neurodegenerative disorder. The RNA/DNA-binding proteins fused in sarcoma (FUS; also known as TLS) and TAR DNA binding protein-43 (TDP-43) have recently been shown to be genetically and pathologically associated with familial forms of ALS and FTD. It is currently unknown whether perturbation of these proteins results in disease through mechanisms that are independent of normal protein function or via the pathophysiological disruption of molecular processes in which they are both critical. Here, we report that Drosophila mutants in which the homolog of FUS is disrupted exhibit decreased adult viability, diminished locomotor speed, and reduced life span compared with controls. These phenotypes were fully rescued by wild-type human FUS, but not ALS-associated mutant FUS proteins. A mutant of the Drosophila homolog of TDP-43 had similar, but more severe, deficits. Through cross-rescue analysis, we demonstrated that FUS acted together with and downstream of TDP-43 in a common genetic pathway in neurons. Furthermore, we found that these proteins associated with each other in an RNA-dependent complex. Our results establish that FUS and TDP-43 function together in vivo and suggest that molecular pathways requiring the combined activities of both of these proteins may be disrupted in ALS and FTD.

SOLUTION:
The ALS-associated proteins FUS and TDP-43 function together to affect Drosophila locomotion and life span.
