The Dysfunctional Attitude Scale: How well can it measure depressive thinking?

The Dysfunctional Attitude Scale (DAS) was designed to measure patterns of maladaptive thinking held by depressed individuals. Despite its wide use as a research and clinical tool, only a few studies to date were designed to examine its psychometric properties in a clinically depressed population. Moreover, problems of low sample size and limited tests of validity call these findings into question. The present study was designed to examine psychometric properties of the DAS in clinically depressed inpatients and in nondepressed clinical controls. Intertest correlations between the DAS parallel forms and between each form with total test scores ranged from r=.84 to r=.97. Intratest stability coefficients were r=.88 to r=.97. Support for the DAS as a valid measure of dysfunctional cognitions in depressed patients was also indicated. Of those scoring high on the DAS, 73% received an independent RDC diagnosis of clinical depression, while only 36% of those receiving low DAS scores were so diagnosed.     

Typing letter strings varying in orthographic structure

Subjects typed six-letter strings varying in orthographic structure. Lexical status, word frequency, position-sensitive log bigram frequency, and regularity of letter sequencing were systematically varied. Cumulative reaction times (RTs) of the keystrokes were adequately described by a linear function of letter position in the test string. Overall, words were typed faster than nonwords, and regular strings faster than irregular strings. Although the effect of log bigram frequency was not significant, this variable interacted with regularity and word frequency. Post hoc analyses of performance on each of the 200 letter strings revealed significant effects of the number of irregularities, log bigram frequency, and log word frequency. Transition times between successive keystrokes were significantly longer for illegal than for legal letter transitions. These results are similar to previous findings on the role of orthographic structure in the perceptual recognition of letter strings and provide a more complete analysis of context effects in typing.     

The contribution of vowel duration,F0 contour,and frication duration as cues to the/juz/-/jus/distinction

A model was quantified to describe the integration of vowel duration, fricative duration, and fundamental frequency (F₀) contour as cues to final position fricatives differing in voicing. The basic assumptions are that perceived vowel duration and perceived frication duration are cues to the identity of final position fricatives and that both F₀ contour and vowel duration influence perceived vowel duration. Binary choice and rating responses to synthetic stimuli varying independently along the three dimensions were collected. The results were consistent with the assumption that F₀ contour operates by modifying perceived vowel duration, which is a direct cue. Unfortunately, the nature of the modification appears to be very similar in form to that which results from the integration of two independent cues in syllable identification. Therefore, the results do not allow a rejection of the idea that the perception of F₀ contour may directly cue the identity of final position fricatives.     

Selective perception without confounding contributions of decision and memory

Previous research has demonstrated that decision processes and short-term memory limitations contribute to the observed limitation in the span of apprehension in tachistoscopic experiments. The present study addresses the question of whether perceptual factors also contribute to this limitation. Observers were asked to indicate which of four target letters occurred in a four-item test display. The irrelevant background items were either highly confusable or completely nonconfusable with the target letters. The target detection task is designed to bypass short-term memory limitations. In order to eliminate differences in decision processing, the location of the target letter was indicated either slightly before or shortly after the display presentation. The indicator was either an arrow cue or a pattern mask. Performance decreased with increases in the delay of the arrow cue only when the background items were confusable. The pattern mask yielded standard masking functions, but performance with the nonconfusable background items improved more rapidly with increases in processing time than did performance with the confusable background items. These results conform to the hypothesis that attention operates at the perceptual stage of processing. The results were accurately described by a quantification of attentional effects in a general information processing model.     

Family work for schizophrenia: some issues for Chinese immigrant families

This paper discusses some specific issues relevant to immigrant Chinese families in the context of family work for schizophrenia. The issues include shame and guilt, isolation and mistrust of officials, the importance of negotiation before details of problem-solving are worked out, high academic ambitions for children, and apparent ‘overprotectiveness’ in the Chinese culture. It is argued that cognitive-behavioural, goal-orientated family work could be adapted well for immigrant Chinese families with a member suffering from schizophrenia. A case study is presented to illustrate how such a family was helped.     

Interrogative suggestibility: The effects of sleep deprivation and relationship with field dependence

Suggestibility (yield) scores on the first Gudjonsson Suggestibility Scale were found to correlate significantly with field dependence, as measured by the Finding Embedded Figures Test. Sleep-deprived subjects, while scoring worse on story memory, reaction time, POMS vigour–energetic and POMS confusion than controls, did not show any increase in yielding to suggestive questions. Upon answering the questions again after negative feedback, however, sleep-deprived subjects shifted their responses to questions significantly more than did controls. The results are interpreted in terms of sleep loss increasing the variability of performance.

Identification as an organizational anchor: how identification and job satisfaction combine to predict turnover intention

The article examines the role of organizational identification and job satisfaction in relation to turnover intentions in seven organizations. Two models are proposed in which either job satisfaction or organizational identification was treated as a mediator of the other's relationship with turnover intention. The organizations varied in terms of culture (Japan vs. UK), and institutional domain (academic, business, health, mail, legal). Within each organization, and meta‐analytically combined across the seven samples (N = 1392), organizational identification mediated the relationship between job satisfaction and turnover intention more than job satisfaction mediated the relationship between organizational identification, and turnover intention. Organizational identification also had the larger overall relationship with turnover intention. This pattern remained true when gender, age, type of organization, culture, and length of tenure were accounted for, although the direct relationship between job satisfaction and turnover intention was stronger in private than public organizations and when the ratio of men was higher. The findings are consistent with a social identity theory (SIT) perspective and with the idea that identification is a more proximal predictor of turnover intention. Over and above job satisfaction, organizational identification offers a strong psychological anchor that discourages turnover intention in a range of organizational contexts.

Reduced approach motivation following nonreward: Extension of the BIS/BAS scales

The current study describes the development and validation of a new subscale to be used with the BIS/BAS scales (Carver & White, 1994). This subscale measures lowered approach motivation following nonreward. Factor analysis of the new subscale was carried out within a sample of 308 University students, test–retest reliability was established within a sample of 62 individuals, and construct validity was explored in a sample of 86 individuals by comparing scores on the new subscale with those on an existing self-report measure of apathy and on a behavioural measure of persistence. Reliability and validity of the new frustrative nonreward responsiveness subscale was found to be adequate within the populations studied. The findings are discussed in relation to theoretical accounts of BAS and BIS sensitivity.     

Microstructural analysis of ingestive behaviour reveals no contribution of palatability to the incomplete extinction of a conditioned taste aversion

An analysis of the microstructure of licking responses was used to investigate the effects of conditioning and extinguishing a taste aversion. Rats received a single pairing of 8% fructose with lithium chloride (LiCl) while controls received unpaired exposure to fructose and LiCl. Pairing fructose with LiCl produced a reduction both in consumption and in the size of licking clusters. Subsequent exposure to fructose in the absence of LiCl produced some extinction of the taste aversion although at asymptote there was a residual difference in consumption between the taste aversion group and unpaired controls. In contrast the reduction in lick cluster size did completely extinguish. Previous analyses of licking microstructure indicate that lick cluster size is related to the palatability of the ingested solution. Thus these results indicate that although taste aversion learning initially reduces the palatability of the cue solution this reduction is not permanent. These results are discussed with reference to the possibility that preparatory behaviours are more resistant to extinction than are consummatory behaviours.
