The Test of Variables of Attention (TOVA): Internal Consistency (Q1 vs. Q2 and Q3 vs. Q4) in Children with Attention Deficit/Hyperactivity Disorder (ADHD)

The internal consistency of the Test of Variables of Attention (TOVA) was examined in a cohort of 6- to 12-year-old children (N = 63) strictly diagnosed with ADHD. The internal consistency of errors of omission (OMM), errors of commission (COM), response time (RT), and response time variability (RTV) of different test conditions (stimulus infrequent condition [Q₁ vs. Q₂] and stimulus frequent condition [Q₃ vs. Q₄]) was assessed via correlation analyses. All TOVA index scores under investigation assessing its internal consistency exhibited statistically significant correlations. All correlations fell in the moderate-high range.     

Does the Chinese construct of guan export to the West?

This study reverses the usual process of assessing universality by examining whether a construct originating in non‐western cultures has functional relevance in the West. The construct of guan or “training” was proposed by Chao (1994) as reflecting important Chinese parenting practices also shared by other Confucian cultures. She proposed that this construct is more relevant to the understanding of outcomes among Asian‐American youth than constructs that have been developed in the West, such as “authoritative” parenting. The association among the behaviours incorporated in this construct and other “universal” parenting styles such as parental warmth has not been previously reported. Nor has there been a previous report of the prevalence and perceived desirability of guan behaviours from Western individuals. Participants in the present study were US (N = 118), Hong Kong (N = 171) and Pakistani (N = 98) nursing students. In all three cultures, guan items had adequate internal consistency (Cronbach's alphas ranging from .69 to .76), associated positively with parental warmth (Pearsons' r ranging from .37 to .52), and were seen as attributes of ideal parents. Mothers in all three cultures were perceived as showing more guan than fathers show. The associations between parental guan and the outcomes of perceived health, relationship harmony and life satisfaction were significant for the Asian participants. Tests of guan's functional relevance in the West had equivocal results with weak associations to positive outcomes in the West compared to Asia. However, the differences between cultures did not reach statistical significance. When the cultures were merged, parental training perceptions predicted a significant proportion of the variance in outcomes. Mothers' guan predicted self‐esteem in their children, whereas fathers' guan predicted life satisfaction. Although guan may have emerged from a Chinese cultural context, it appears to function similarly in many cultural systems, and may represent the Asian face of authoritative parenting.     

A cross-cultural investigation of cognitions and depressive symptoms in adolescents

Adolescents (N=2,272) from Hong Kong and the United States provided information regarding their depressive symptoms, cognitions (self-efficacy, negative cognitive errors, and hopelessness), and stressful events between 2 surveys 6 months apart. Depressive symptoms and hopelessness were higher, and self-efficacy and negative cognitive errors were lower in Hong Kong than in the United States. Cognitions were associated with concurrent depressive symptoms and predicted depressive symptoms 6 months later in both cultures. The "reverse" model was also supported with more variance predicted by depressive symptoms to later cognitions than from cognitions to depressive symptoms. There was some support for the hypothesis that self-efficacy is less salient in collective compared with individualistic cultures. These findings extend cognitive theories of depression to a non-Western culture.     

Nonadherence in Adolescent Oncology Patients: Preliminary Data on Psychological Risk Factors and Relationships to Outcome

Published nonadherence rates in the adolescent oncology population range from 33 to 60% though little is known about the psychological factors that contribute to adherence and the relationship between outcome and nonadherence. Our study was designed to investigate psychological and family factors related to adherence and the relationship between adherence and survival in this population. We evaluated 44 (27 males, 17 females) patients with cancer (13–17 years) who were at least 6-months postdiagnosis. Adherence with trimethoprim/sulfamethoxazole (TMP/SMX) was determined at one point in time, using serum assay. Twelve of the patients (27%) had no detectable TMP/SMX. Patients without detectable drug had higher levels of depression, lower self-esteem, and higher levels of parent–child incongruence. Survival rates, 6 years after the initiation of the study, were lower in the group of participants categorized as nonadherent. These findings, if confirmed, have implications for the management of nonadherence and mood in this population.
