Análisis Estructural de la Escala de Afrontamiento ante la Ansiedad e Incertidumbre Pre-examen (COPEAU) en universitarios peruanos RESUMEN. El objetivo de la presente investigación fue analizar la estructura interna de la Escala de Afrontamiento ante la Ansiedad e Incertidumbre Pre-examen (COPEAU) en universitarios peruanos de una institución privada. Participaron 312 estudiantes de la carrera de psicología (227 mujeres) del 1er al 6to ciclo, con edades entre 16 y 49 años (M = 20.54; DE = 4.29). Con la metodología de ecuaciones estructurales fueron evaluados cinco modelos, de los cuales el de cuatro factores oblicuos presenta mayor coherencia teórica y empírica. Del mismo modo, los indicadores de confiabilidad son apropiados. Las implicaciones prácticas de los resultados en el marco de una teoría más amplia de afrontamiento al estrés fueron discutidas, así como la pertinencia de algunos procedimientos en los estudios de aproximación analítico-factorial. ABSTRACT. The objective of this research was analyze the internal structure of Coping with PreExam Anxiety and Uncertainty (COPEAU) in Peruvian college students from a private institution. Participated 312 psychology students (227 women) from from the first to sixth term, with age between 16 and 49 (M = 20.54; SD = 4.29). Using the structural equation modeling, five models were assessed, among which the four oblique factor model shows greater theoretical and empirical coherence.. Also, the reliability indices were appropriate. The practical implications of the results in the context of a broader theory of coping with stress were discussed, as well as the relevance of some procedures in analytical studies-factorial approach.

The performance of four rules for determining the number of components to retain (Kaiser's eigenvalue greater than unity, Cattell's SCREE, Bartlett's test, and Velicer's MAP) was investigated across four systematically varied factors (sample size, number of variables, number of components, and component saturation). Ten sample correlation matrices were generated from each of 48 known population correlation matrices representing the combinations of conditions. The performance of the SCREE and MAP rules was generally the best across all situations. Bartlett's test was generally adequate except when the number of variables was close to the sample size. Kaiser's rule tended to severely overestimate the number of components.

An interest in reducing relapse among alcoholics has led to a consideration of stimulus control factors in drinking. Research suggests that through classical conditioning alcoholics may develop reactions to cues previously associated with drinking and that these reactions might be an important determinant of relapse. Although this model indicates the potential for cue exposure treatment methods to alter conditioned reactions, data on reactivity to alcohol cues by alcoholics and nonalcoholics are scarce. Two studies are presented that address this issue and provide evidence for the validity of salivation as a measure of cue reactivity. Alcoholics and nonalcoholics were presented with the sight and smell of their preferred brand of alcohol and a control beverage. Self-report, behavioral, and psychophysiological data were collected. Alcoholics salivated more than nonalcoholics to alcohol cues and more to alcohol than to the control beverage. Alcoholics salivated differentially to cues, whereas nonalcoholics did not. Patterns of reactivity were consistent with a conditioning model. Both groups reported greater urges to drink alcohol in the presence of alcohol, but neither group reported more thoughts about alcohol in the presence of alcohol as compared with the control beverage. Implications of salivary reactivity for theory and treatment are discussed.Relapse prevention among individuals treated for problem drinking continues to challenge clinicians and researchers.Prompted in part by clinical observation, theoretical discussions have suggested that setting cues or stimulus control factors may be relevant to this complex problem. Several reports have indicated that strong reactions may be conditioned to stimuli that are repeatedly paired with substance use and, in turn, that these reactions may contribute to craving, tolerance, and nonpharmacological aspects of withdrawal symptoms (Cooney,
