Applying a longitudinal tracer methodology to evaluate complex interventions in complex settings

Long-running multi-faceted intervention studies are particularly problematic in large complex organizations where traditional methods prove too resource intensive and can yield inaccurate and incomplete findings. This paper describes the first use of, longitudinal tracer methodology (LTM), a realist approach to evaluation, to examine the links between multiple complex intervention activities (processes) and their outcomes on a construction megaproject. LTM is especially useful when the researcher has little control over intervention delivery but has evidence drawn from multiple sources to evaluate the intervention activities effects over time. This methodology has rarely been deployed in complex organizational settings and not on a construction megaproject. This paper presents a case study of its use over a period of three years, on 24 construction sites forming London’s Thames Tideway Tunnel (Tideway) megaproject. The study examines the “transformational” power of occupational safety and health (OSH) interventions across the multiple organizations and supply chains in the megaproject. The study shows how the method can be adapted in-flight to accommodate shifting lines of inquiry as the intervention activities progress and change. This feature along with its resource-efficient operation, make it an attractive option where interventions are likely to have differential effects across multiple sites of enactment.     

Positive and problematic dissertation experiences: The faculty perspective

We interviewed 14 clinical and counseling psychology faculty regarding their experiences chairing positive and problematic dissertations. Data were analyzed using consensual qualitative research (CQR). Participants reported that advisors’ roles involved guiding/facilitating dissertations and helping students shape research ideas; students’ roles included taking responsibility, working independently, and maintaining good relationships with the chair/committee. With positive dissertation experiences, chairs and students collaborated before the dissertation, worked together well during the dissertation, and students began the dissertation feeling competent and motivated; such dissertations positively affected participants. Problematic dissertation experiences evinced difficult relationships between chair and student, and students’ low research capability; such dissertations negatively affected participants.     

Trait Anger and Axis I Disorders: Implications for REBT

Anger has a prominent role in basic theories of emotion. And while many psychiatric disorders can be conceived of as emotional disorders (e.g., depressive disorders, anxiety disorders), there are no disorders for which anger is the cardinal feature. We analyzed diagnostic data on 1,687 (as later) psychiatric outpatients and looked at the co-occurrence of high trait anger (as assessed by criterion 8 of Borderline Personality Disorder) and Axis I disorders, and Borderline and Antisocial Personality Disorders. The purpose was to examine whether dysfunctional anger met criteria necessary to be considered a valid diagnostic category. Results showed that high trait anger was not fully accounted for by any particular Axis I diagnosis, or any set of Axis I diagnoses, or by the combination of Axis I diagnoses and Borderline and Antisocial PDs. Trait anger also accounted for significant amounts of unique variance in several indicators of psychiatric impairment and psychosocial functioning. We describe the anger disorder diagnoses of Eckhardt and Deffenbacher (Anger disorders: Definition, diagnosis and treatment. Taylor & Francis, Bristol, PA, 1995), and discuss the implications of those diagnoses for the practice of REBT and CBT.

Relation of Self-Efficacy to Reported Pain and Pain Medication Usage During Labor

We studied the relationship of self-efficacy to reported labor pain and pain medication usage among 43 women. Self-efficacy ratings were judgments of confidence regarding successful completion of tasks involved in labor and delivery (e.g., doing breathing exercises) and in overcoming barriers (e.g., nonsupportive partner). Multiple regression analyses revealed that self-efficacy significantly contributed to predicting labor pain beyond other relevant variables (e.g., age, amount of menstrual pain), with barrier self-efficacy the strongest predictor. Results are discussed in the context of increasing women's confidence in overcoming barriers by incorporating relevant interventions in childbirth education.     

Mood-congruent memory in depression: emotional priming or elaboration?

We investigated whether mood-congruent memory (MCM) bias in depression is a function of implicit or explicit memory. Implicit memory is taken as a measure of ease of activation, whereas explicit memory also taps elaboration. As expected, MCM bias was found in the explicit memory task but not in the implicit memory task. We believe this finding supports the involvement of elaborative mechanisms in MCM. In addition, memory bias was found with words related to depression but not with words denoting physical threat. Thus, the MCM bias in explicit memory was found to be specific to information that was congruent with depression rather than to all negative information.     

Selection of vigilant and avoidant coping strategies among repressors, highly anxious and truly low anxious subjects

70 female graduate students from a western university were classified as to personality type: Highly Anxious, Truly Low Anxious, and Repressing, using a combination of scores from the Taylor Manifest Anxiety Scale and the Marlowe-Crowne Social Desirability Scales. Each subject's preference for monitor or blunter coping strategy was assessed via the Miller Behavioral Style Scale. Highly Anxious subjects chose significantly more monitor strategies than did Truly Low Anxious subjects or Repressors. The number of blunter strategies chosen did not differ across personality types. Chi-squared indicated that Highly Anxious subjects were more often classified as monitors than blunters whereas the proportions of monitors and blunters did not significantly differ between Truly Low Anxious subjects and Repressors. Results suggest that the repressor trait is distinct from avoidant and vigilant coping strategies.     

Hemisphere functioning and motor imitation in autistic persons

Previous research has found that a high proportion of autistic individuals exhibit an atypical pattern of hemispheric specialization suggestive of impaired left hemisphere functioning: namely, right hemisphere dominance for both verbal and visual-spatial processing. Studies of brain-damaged persons have suggested that the left hemisphere is specialized for the use of nonverbal gesture. Since a major characteristic of autism is an impairment in the use of gesture, it was predicted that autistic persons would also show atypical hemispheric specialization for motor imitation. To test this hypothesis, hemispheric activation was measured using EEG recordings of alpha rhythm in autistic and matched normal control subjects during four motor imitation tasks. Autistic subjects showed significantly greater right hemisphere activation during the imitation tasks, than normal subjects. This pattern was particularly evident in younger autistic subjects and during oral, rather than manual, imitation tasks.
