Who uses community mental health centres? A study of one health district

A caseload analysis was undertaken to investigate those clients seen by five community mental health centre teams within one healthcare district. The 985 clients are described in terms of demographic and clinical features and questions relating to service provision are discussed.     

An investigation into the relationship between perceived control,attitude variability and the consumption of two common foods

The study reported here takes its lead from the literatures which emphasize the importance of attitude variability and the role of perceived control over action. Within-person variability and perceptions of control are investigated in the context of people's attitudes towards the consumption of two common foods. The role of attitude ambivalence is also examined. The findings indicate that higher attitude variability is associated with weaker relationships between the components of the theory of reasoned action and that attitude variability is negatively related to perceived control. Moreover, perceived control is shown to be related to different sorts of control problem for different behaviours. It is advocated that a more in-depth assessment of attitude variability and the perceived control construct is merited and that recent calls for more serious examination of attitude ambivalence are well-founded.     

Primacy of dimensions in vibrotactile perception: An evaluation of early holistic models

Early holistic models of perception presume that stimuli composed of interacting dimensions can be experienced initially as undifferentiated. This view, formalized through recourse to a Euclidean geometry of perceptual space, predicts that the orientation of axes used to create stimulus sets is unimportant to performance in speeded classification. We tested this idea by using the interacting vibrotactile dimensions of pitch and loudness. Despite perceivers’ relatively poor experience with these dimensions, we showed that the orientation corresponding to pitch and loudness was unique in vibrotactile perceptual space; subjects classified stimuli more efficiently at this orientation than at other orientations. Certain holistic models also claim that when stimulus differences are small, perceivers can recognize change without distinguishing the kind of change. We tested this idea by using a signal detection analysis of unspeededsame—different decisions. We found that subjects’ ability to notice the kind of change equaled their ability to notice the change alone. In view of these results, which indicate that pitch and loudness are primary in vibrotactile perception, we detail a new conception of dimensional interaction.     

Neurological soft signs and school achievement: The mediating effects of sustained attention

A group of 115 black male adolescents drawn from a clinically unselected birth cohort, half of whom were known to have had neurological soft signs at age 7, were examined at age 17 to determine the relation between soft signs and performance on standard tests of school achievement and sustained attention. Three signs measured at age 17-dysgraphesthesia, difficulties with rapid alternating movements (dysdiadochokinesis), and motor slowness—were related to lower concurrent and past IQ and to impaired performance on laboratory and paper-and-pencil measures of sustained attention. The relation between signs and the attentional measures remained significant after IQ was statistically controlled. The three age 17 soft signs as well as age 7 signs were related to impaired performance on standardized tests (age 17) of school achievement. Most of the relation between signs and school achievement could be accounted for by the variance signs shared with sustained attention. One sign, mirror movements, was unrelated to all other attentional and cognitive measures.The study was supported by center grant MH 306906 and research training grant 5 T32 MH 13043-13 from the National Institute of Mental Health, as well as by the City College and the City University Computing Centers. We thank Lillian Belmont and two reviewers for their critical comments on an earlier version of the paper. We dedicate this paper to the memory of Joseph Barmack.     

Continuities in the development of the physical and social sciences: Principles of a new social physics

The original concept of “social physics” was built on positivist philosophy and scientific method. Evidence from quantum physics suggests that a postpositivist “social physics” may yet be viable, not because social science should emulate physics, but because physics is more like social science. The five principles of complementarty, uncertainty, the measurement problem, nonlocal causation, and participatory collusion are presented in this article to demonstrate the contemporary convergence of the physical and social sciences into a new social physics. E. Sam Overman is associate professor of public affairs at the Graduate School of Public Affairs, University of Colorado at Denver, Denver CO 80204. He recently editedMethodology and Epistemology for Social Science, selected papers by Donald T. Campbell (University of Chicago Press, 1988). He has published other articles on policy physics and social science philosophy, and has conducted research and published extensively in the area of information resource policy and management.     

Probability of relapse after recovery from an episode of depression

Examined relapse rates in those individuals who have experienced an episode of unipolar depression as a function of the number of previous episodes, gender, age at onset of the episode (less than 40 vs. greater than 40), time since a previous episode, and depression level at time of interview. From of 6,742 participants, 2,046 were interviewed; of these, 1,130 had at least one, 513 reported a second and 173 reported a third episode. The probability for relapse was positively related to number of previous episodes, being female, depression level at time of interview, but not to age at onset (less than 40 vs. greater than 40). Women were also more likely to have more severe episodes. Participants with elevated depression symptoms reported a greater number of previous episodes. Following the first episode, there was a decline in hazard rate for men but not women; following the second episode, there was no change in vulnerability for men; for women, the results were ambiguous.     

Metaphors do not use associations between concepts,they are used to create them

Does the interpretability and aptness of a metaphor depend on prior existing associative relations between the metaphor topic and vehicle? Lexical decision latencies for pairs of words drawn from apt, comprehensible metaphors were no faster than latencies for randomly paired words. In contrast, lexical decision latencies for associatively related word pairs were faster than latencies for randomly paired words. These data suggest that good metaphors do not use preexisting associations to achieve their effects. Instead, we argue tht people use metaphors to create new relations between concepts. Implications for a theory of metaphor comprehension are discussed.     

Parent and child adjustment dual trajectories at the beginning of the COVID-19 syndemic

Children and their families have been significantly impacted by the unfolding of the COVID-19 syndemic. We sought to identify (1) groups of families with distinct profiles of joint trajectories of parental anxiety and child emotional distress and (2) protective and risk factors associated with these dual-trajectory profiles. A sample of 488 parents (65% White; 77% mothers) with 3- to 8-year-old children (M_Age = 5.04, SD_Age = 1.59) was followed from late March to early July in 2020. Survey data on parent (i.e., anxiety symptoms) and child (i.e., emotional distress) adjustment were collected at three time points. Using multivariate growth mixture modeling, we identified one group with low parental anxiety and child emotional distress (42.7%) and three other distinct groups with varying risk levels among parents and/or children. We also identified protective (e.g., positive parenting) and risk (e.g., child negative affect, negative parenting, perceived stress with racism) factors in predicting parent and child adjustment. It can be concluded that, overall, our sample (mostly middle- and high-socioeconomic status families) demonstrated family resilience amid COVID-19, consistent with prior disaster coping literature. At the same time, our findings also indicated the need to identify at-risk families and modifiable factors for post-disaster public health interventions.
