Helping Police Officers to Cope with Stress: A Cognitive—Behavioral Approach

Police Academy trainees participated in a stress management program which focused on developing skills for coping with anxiety and anger. Stress management training took place in six 2-hour sessions and included instruction and practice in the self-monitoring of reactions to stressful situations, muscular relaxation, and the development of adaptive self-statements. Self-report measures of anxiety and anger were obtained before and after the stress management program. In addition, self and observer ratings of trainees' performance in stressful simulated police activities were utilized as posttreatment dependent measures. In comparison to a control group of trainees, the performance of the treatment group was rated, by academy personnel, as superior in several of the simulated police activities. The results of the present study suggest that stress management with law enforcement officers may be most effective when the program focuses on the specific situations which are likely to be encountered by trainees. Limitations of the present program are examined and suggestions for future efforts with law enforcement personnel are discussed.     

Identifying international assignees at risk for premature departure: the interactive effect of outcome favorability and procedural fairness

Two studies examined factors that predict expatriate managers' tendencies to think seriously about departing prematurely from their international assignments. Previous research (conducted outside of the expatriate context) has shown that individuals' willingness to stay with or leave their positions is an interactive function of outcome favorability and procedural fairness. A conceptually analogous interaction effect was found in the present studies. Whereas expatriates more seriously thought of departing prematurely when they perceived the non-work-related outcomes of their overseas assignments to be less favorable, this tendency was much less pronounced when procedural fairness was relatively high. Theoretical and practical implications are discussed, as are limitations of the studies and suggestions for future research.     

A person-oriented approach to hand hygiene behaviour: Emotional empathy fosters hand hygiene practice

Objectives: Adopting a social-psychological approach, this research examines whether emotional empathy, an affective reaction regarding another’s well-being, fosters hand hygiene as this affects other’s health-related well-being extensively.

Design: Three studies tested this notion: (a) a cross-sectional study involving a sample of health care workers at a German hospital, (b) an experiment testing the causal effect of empathy on hand hygiene behaviour and (c) an 11-week prospective study testing whether an empathy induction affected disinfectant usage frequency in two different wards of a hospital.

Main outcome measures: Self-reported hand hygiene behaviour based on day reconstruction method was measured in Study 1, actual hand sanitation behaviour was observed in Study 2 and disinfectant usage frequency in two different hospital wards was assessed in Study 3.

Results: Study 1 reveals an association of empathy with hand hygiene cross-sectionally, Study 2 documents the causal effect of empathy on increased hand sanitation. Study 3 shows an empathy induction increases hand sanitiser usage in the hospital.

Conclusions: Increasing emotional empathy promotes hand hygiene behaviour, also in hospitals. Besides providing new impulses for the design of effective interventions, these findings bear theoretical significance as they document the explanatory power of empathy regarding a distal explanandum (hand hygiene).     

Demands and capacities or demands and performance?

The Demands and Capacities Model of stuttering purportedly provides a framework for obtaining information concerning a child's capacities for fluency and the demands placed on the child by the environment and for integrating that information in devising individual therapy plans. The current paper analyzes the model, with specific attention to the status of the “capacities” component. It is suggested that the model is more accurately characterized as a Demands and Performance rather than a Demands and Capacity Model because capacities are not actually addressed.     

Neurochemical mechanisms underlying amygdaloid modulation of aggressive behavior in the cat

Studies designed to determine the respective roles of substance P, excitatory amino acids, and enkephalins in amygdaloid modulation of defensive rage behavior in the cat are presented. The basic design of these studies involved three stages. In stage I, cannula electrodes for stimulation and drug infusion were implanted into medial hypothalamic or midbrain periaqueductal gray (PAG) sites from which defensive rage behavior could be elicited. Then, a stimulating electrode was implanted into a site within the medial, basal, or central nuclear complex from which modulation of the defensive rage response could be obtained. Amygdaloid modulation of defensive rage was determined in the following manner: it employed the paradigm of dual stimulation in which comparisons were made of response latencies between alternate trials of dual (i. e., amygdala = medial hypothalamus [or PAG]) and single stimulation of the hypothalamus or PAG alone. Thus, stage I established the baseline level ofmodulation (i. e., facilitation or suppression of defensive rage) in the predrug stimulation period. In stage II, a selective or nonselective receptor antagonist for a given transmitter system was administered either peripherally or intracerebrally at the defensive rage site, after which time the same dual stimulation paradigm was then repeated over the ensuing 180 min postinjection period in order to determine the effects of drug delivery upon amygdaloid modulation of defensive rage. Stage III of the study took place at the completion of the pharmacological testing phase. The retrograde axonal tracer, Fluoro-Gold, was microinjected into the defensive rage site within the medial hypothalamus or PAG, and following a 6-14 day survival period, animals were sacrificed and brains were processed for histological and immunocytochemical analyses for the neurotransmitters noted above. This procedure thus permitted identification of cells within the amygdala which were labeled retrogradely and which were also immunostained positively for substance P, excitatory amino acids, or enkephalin. For studies involving substance P, defensive rage was elicited from the medial hypothalamus and for studies examining the roles of excitatory amino acids and enkephalin, defensive rage was elicited from the PAG. In the first study, facilitation of hypothalamically elicited defensive rage was obtained with dual stimulation of the medial nucleus of the amygdala. In separate experiments, the selective NK₁ non-peptide antagonist, CP 96,345, was administered both peripherally as well as intracerebrally into the hypothalamic defensive rage sites in doses of 0.5-4.0 mg/kg (i. p.) and 0.5-2.5 nmol (i. c.). Following drug delivery, the facilitatory effects of medial amygdaloid stimulation were blocked in a dose- and time-dependent manner in which the effects were noted as early as 5 min postinjection. The maximum drug dose (4.0 mg/kg) employed for peripheral administration resulted in a 42% reduction in the facilitatory effects of the medical amygdala (P < 0.002). This drug, when microinjected directly into medial hypothalamic defensive rage sites at the maximum dose level of 2.5 nmol, resulted in an 84% reduction of the suppressive effects of amygdaloid stimulation (P < 0.5) at 5 min postinjection. In the next study, an N-methyl-D-aspartate (NMDA) antagonist, DL-α-amino-7-phosphonoheptanoic acid (AP-7), was administered either peripherally (0.1-1.0 mg/kg) or intracerebrally (0.2 and 2.0 nmol) into PAG defensive rage sites. Facilitation of defensive rage behavior, which was observed following dual stimulation of the basal amygdala and PAG, was significantly reduced by either route of drug administration in a dose- and time-dependent manner. At the maximum dose level of peripheral administration, AP-7 reduced amygdaloid facilitation of defensive rage by 63% (P < 0.001) for 60 min, postinjection. A smaller (i. e., 19%) but still significant (P < 0.05) reduction in facilitation was obtained following intracerebral administration of the drug. In a third study, the non-selective opioid receptor antagonist, naloxone (27.5 nmol), infused directly into PAG defensive rage sites, totally blocked the suppressive effects of central amygdaloid stimulation for a period of 30 min (P < 0.05) in a dose- and time-dependent manner. The anatomical phase of this study revealed the following relationships: 1) that large numbers of neurons projecting to the medial hypothalamus from the medial amygdala immunoreact positively for substance P; 2) that neurons projecting to the PAG from the basal complex of amygdala immunoreact positively for glutamate and aspartate; and 3) that neurons located within the central nucleus of the amygdala which project to the PAG immunoreact positively for met-enkephalin. Collectively, these observations provide new evidence which characterizes the likely neurotransmitters linked with specific amygdaloid pathways subserving the modulation of defensive rage behavior in the cat.     

Positive emotion infusions of elevation and gratitude: Increasing help-seeking intentions among people with heightened levels of depressive symptomatology

Three online studies assessed a new approach for increasing help seeking among people with depressive symptomatology (i.e. a positive emotion infusion, PEI). A PEI refers to the induction of positive emotion such that people’s mindsets – including perceptions of help-seeking – are temporarily altered. Study 1 (n = 382) indicated that help-seeking intentions are negatively correlated with depressive symptomatology and positively correlated with elevation and gratitude. Studies 2 and 3 implemented fully randomized experimental designs. In Study 2, two elevation-based (Study 2a, n = 285) and two gratitude-based (Study 2b, n = 338) emotion inductions increased levels of elevation and gratitude, respectively. Results of Study 3a (n = 390) indicate a causal relationship between experiencing the story-based elevation induction and increased help-seeking intentions. The two gratitude-based PEIs (Study 3b, n = 466) were unsuccessful at influencing help-seeking; auxiliary analyses indicate the possibility of iatrogenic effects. Overall, the potential of PEIs was indicated, as was need for caution.     

Occasion Setting and Drug Tolerance

There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that it should be possible to establish drug-paired cues as occasion setters, as well as conditional stimuli. Using feature-positive discrimination training, we evaluated the contribution of occasion-setting stimuli (as well as CSs) to tolerance to the hypothermic effect of ethanol in rats. The results indicated that a complete associative analysis of drug tolerance should incorporate not only the CS properties of predrug cues, but also the occasion-setting properties of such cues. The findings have implications for interpreting conflicting findings concerning extinction of tolerance and for cue-exposure treatments of addiction.
