Fatigue in the workforce of National Health Service Trusts: levels of symptomatology and links with minor psychiatric disorder, demographic, occupational and work role factors.

The aims of this study were: (1) to obtain a systematic estimate of the levels of fatigue in representative samples of the major occupational groups of health care workers; (2) to examine the relationship between fatigue and mental health as a function of occupational and work role factors; and (3) to test the proposition that fatigue arises from a combination of poor mental health and high job stress. Questionnaire data from 7720 NHS Trust staff was used. Higher levels of fatigue were reported among health care workers in comparison with general population figures. Highest levels of general fatigue, the subjective sensation of tiredness, were experienced by doctors (especially women doctors), professions allied to medicine and managers. Highest levels of fatigability, the onset of symptoms after exertion, were experienced by ancillary and nursing staff. Both general fatigue and fatigability were associated with high levels of psychological distress. Support was also found for the proposition that fatigue arises from a combination of poor mental health and high work demands.

A comparative analysis of the therapeutic focus in cognitive-behavioral and psychodynamic-interpersonal sessions.

This study compared therapeutic foci in a sampling of 30 cognitive-behavioral and 27 psychodynamic-interpersonal manual-driven treatments for depression. High- and low-impact sessions were coded for each client, with the Coding System of Therapeutic Focus. Results indicated that psychodynamic-interpersonal sessions focused more on such variables as emotion, patterns, incongruities, the impact that others made on clients, clients' expected reaction of others, the tendency to avoid therapeutic progress, therapists themselves, clients' parents, and links between people and time periods in clients' lives. Cognitive-behavioral sessions placed greater emphasis on external circumstances and clients' ability to make decisions, gave more support and information and encouraged between-session experiences, and focused more on the future. Relatively few differences emerged as a function of session impact. Results are discussed in terms of the different and similar theoretical conceptions of the change process.

Minor psychiatric disorder in NHS trust staff: occupational and gender differences.

BACKGROUND: It is widely suggested that many National Health Service (NHS) workers experience high levels of minor psychiatric disorder. However, inadequacies of sampling and measurement in studies to date have not allowed this suggestion to be properly evaluated. METHOD: The present study was designed to overcome these methodological weaknesses by using a sample of over 11,000 employees from 19 NHS trusts and a well-established measure of minor psychiatric disorder for which there are comparative data. RESULTS: The findings show that 26.8% of the health service workers reported significant levels of minor psychiatric disorder, compared with 17.8% of people in the general population. Psychiatric morbidity was highest among managers, doctors, nurses and professions allied to medicine, with each of these groups recording higher rates than their professional counterparts outside the health service. It was lower among those in support occupations, such as administrative and ancillary staff. A feature of the findings was that female doctors and managers showed a much higher prevalence of minor psychiatric disorder than their male colleagues. CONCLUSION: Studies are required to establish the organisational, occupational and individual determinants of minor psychiatric disorder among NHS employees.

Acceleration of changes in session impact during contrasting time-limited psychotherapies.

Following the suggestion that therapeutic change is accelerated in time-limited psychotherapy, this study investigated the across-session patterns of session impact in the treatments of 117 depressed clients who were randomly allocated to 8 or 16 sessions of cognitive-behavioral (CB) or psychodynamic-interpersonal (PI) therapy. After each session, all clients completed the Session Evaluation Questionnaire and 75 of the clients completed the Session Impacts Scale. Session ratings indicated that sessions were perceived increasingly positively on most impact dimensions (e.g., session depth and smoothness, relationship with the therapist, feelings of understanding and problem solving, postsession positive mood) as treatment progressed. Early in treatment, PI therapy sessions were less smooth (i.e., more tense and uncomfortable) and less focused on problem solving, but PI sessions changed more rapidly than CB sessions on these dimensions, so that later in treatment, sessions of both treatments were equivalently positive. In both treatments, the trend toward more positive sessions was more rapid (i.e., the across-session slope was steeper) in 8-session treatments than in 16-session treatments. Such accelerated changes in session impact may reflect the suggested acceleration of therapeutic change associated with shorter time limits.

Outcomes of time-limited psychotherapy in applied settings: replicating the Second Sheffield Psychotherapy Project.

In a replication and extension of the Second Sheffield Psychotherapy Project (SPP2), a collaborative psychotherapy project (CPP) was carried out at 3 sites within the National Health Service of the United Kingdom. Clients (N = 36) stratified at 3 levels of severity of depression were randomly assigned to one of 2 treatment approaches (psychodynamic-interpersonal or cognitive-behavioral) of 2 time-limited durations (8 or 16 sessions). Gains in both treatment approaches were approximately equivalent and were similar for CPP and SPP2 clients when measured at the end of treatment. However, CPP patients did not maintain their gains to the extent that the SPP2 clients did at 3-month and 1-year follow-up assessments. In the CPP, clients given 16 sessions showed a statistically significant advantage over clients given 8 sessions on some measures at some assessments; in the SPP2, similar effects were noted only among some subgroups of clients.

Dose-effect relations in time-limited psychotherapy for depression.

Criteria for reliable and clinically significant improvement were applied to standard and individually tailored outcome measures data from 212 depressed clients who had been randomly assigned to receive either 8 or 16 sessions of time-limiting psychotherapy. The data were used to address 2 questions: (a) Is the dose-effect curve for psychological symptoms negatively accelerated? and (b) is there a differential rate of response for acute, chronic, and characterological/interpersonal components of depression? The results supported the differential rate of response of different components of depression and suggested qualifications to the acute, chronic, and characterological/interpersonal components and evidence that both supported and qualified previous suggestions that the dose-effect curve is negatively accelerated.

Verbal exchange structure of brief psychodynamic-interpersonal and cognitive-behavioral psychotherapy.

A verbal exchange is a set of 2 people's co-occurring speech-act categories that accomplish some subtask within an interpersonal encounter. Factor analysis of verbal response mode (speech act) frequencies in 1,630 segments (each approximately 10 to 12 min) drawn from the brief psychodynamic-interpersonal or cognitive-behavioral treatment of 39 mainly depressed clients identified 6 exchanges in each treatment--4 that were the same in both treatments (Revealing, Storytelling, Explaining, and Inquiring) and 2 that distinguished each treatment (Exploring and Interpreting in psychodynamic-interpersonal treatment; Prescribing and Reframing in cognitive-behavioral treatment). The exchanges showed distinctive temporal patterns across segments of sessions and across sessions of each time-limited treatment. The verbal exchange is a midsize concept that links atomistic verbal codes with clinical or theoretical concepts.

Effects of treatment duration and severity of depression on the maintenance of gains after cognitive-behavioral and psychodynamic-interpersonal psychotherapy.

One hundred four clients completed a mailed follow-up 1 year after completing 8 of 16 sessions of treatment, either cognitive-behavioral (CB) or psychodynamic-interpersonal (PI) psychotherapy. Although mean scores on outcome measures at 1 year suggested that gains were, in general, well maintained, only 29% of clients were asymptomatic on all 3 occasions of testing (end of treatment, 3 months and 1 year later) without recourse to further treatment. However, only 11% of those asymptomatic at end of treatment experienced relapse or recurrence of depression, albeit on the limited evidence of just two follow-up assessments. The results of comparisons among treatment conditions at 1 year differed substantially from those obtained earlier: Eight-session PI treatment now appeared less efficacious than the other 3 treatment conditions, and there was now no measurable benefit of 16-session over 8-session CB, irrespective of initial severity of depression. These findings confirm the importance of follow-up in evaluation of psychotherapies for depression.

Impact of Cluster C personality disorders on outcomes of contrasting brief psychotherapies for depression.

Twenty-seven of 114 depressed clients, stratified for severity of depression, obtained a Diagnostic and Statistical Manual of Mental Disorders (3rd ed.; DSM-III; American Psychiatric Association, 1980) diagnosis of Cluster C personality disorder--that is, avoidant, obsessive-compulsive or dependent personality disorder (PD clients)--whereas the remaining 87 did not (non-personality-disorder [NPD] clients). All clients completed either 8 or 16 sessions of cognitive-behavioral (CB) or psychodynamic-interpersonal (PI) psychotherapy. On most measures, PD clients began with more severe symptomatology than NPD clients. Among those who received PI therapy, PD clients maintained this difference posttreatment and at 1-year follow-up. Among those who received CB therapy, posttreatment differences between PD and NPD groups were not significant. Treatment length did not influence outcome for PD clients. PD clients whose depression was also relatively severe showed significantly less improvement after treatment than either PD clients with less severe depression or NPD clients.

Credibility and outcome of cognitive-behavioural and psychodynamic-interpersonal psychotherapy.

Depressed psychotherapy clients (N = 117) rated the treatment principle credibility of cognitive-behavioural (CB) and psychodynamic-interpersonal (PI) before they were randomly assigned to receive either eight or 16 sessions of one of these treatments, and they rated their expectations of the treatment to which they were assigned immediately before (initial credibility) and immediately after their first session (emergent credibility). Results indicated that before they were assigned to a treatment, clients rated CB treatment principle credibility higher than PI treatment principle credibility. After assignment, however, clients rated initial credibility similar regardless of whether they were assigned to CB or PI therapy, and their ratings of emergent credibility increased to a similar degree from immediately before to immediately after the first session in both treatments. Clients' endorsement of CB and PI treatment principle credibility predicted improvement in PI therapy but not improvement in CB therapy. Initial and emergent credibility of clients' assigned treatment predicted improvement for clients who received eight sessions of therapy, but not for clients who received 16 sessions of therapy. The implications of these findings are discussed.

Therapist contributions to psychotherapeutic assimilation: an alternative to the drug metaphor.

A psychotherapist's verbal interventions may be understood as promoting a client's eventual improvement by facilitating developmental change processes within the client. This approach is an alternative to the traditional search for statistical links between aggregates of therapist interventions and global outcome measures. Our approach employs models of clients' assimilation of problematic experiences within problem domains and therapists' implementation of theoretically specified aims. In an empirical illustration, one client's change within a particular problem domain and its links with therapist interventions were assessed qualitatively across the course of brief psychodynamic-interpersonal treatment.

Effects of treatment duration and severity of depression on the effectiveness of cognitive-behavioral and psychodynamic-interpersonal psychotherapy.

A total of 117 depressed clients, stratified for severity, completed 8 or 16 sessions of manualized treatment, either cognitive-behavioral psychotherapy (CB) or psychodynamic-interpersonal psychotherapy (PI). Each of 5 clinician-investigators treated clients in all 4 treatment conditions. On most measures, CB and PI were equally effective, irrespective of the severity of depression or the duration of treatment. However, there was evidence of some advantage to CB on the Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961). There was no evidence that CB's effects were more rapid than those of PI, nor did the effects of each treatment method vary according to the severity of depression. There was no overall advantage to 16-session treatment over 8-session treatment. However, those presenting with relatively severe depression improved substantially more after 16 than after 8 sessions.

Disabuse of the drug metaphor: psychotherapy process-outcome correlations.

The drug metaphor suggests that if a process component (e.g., interpretation) is an active ingredient of a successful psychotherapy, then administering a relatively high level of it should yield a relatively positive outcome, and levels of the process component and the outcome should be correlated across clients. Measures of 5 theoretically relevant, reliably measured verbal process components were compared with the rate of change in 3 standard symptom intensity measures across the brief treatments of 39 (mainly depressed) psychotherapy clients. The expected significant process-outcome correlations were not found. These results are discussed as they illuminate some misleading assumptions that underlie many conventional studies of psychotherapy process and outcome.

Extended-release felodipine in patients with mild to moderate hypertension. Felodipine ER Dose-Response Study Group.

Two hundred eighty-six patients with mild to moderate hypertension who had untreated diastolic blood pressure while seated of 95 to 115 mm Hg were randomized to receive placebo or once-daily doses of 2.5, 5, or 10 mg of the dihydropyridine calcium channel blocker felodipine extended release (ER). Blood pressure was measured 24 hours after dosing (at trough). Mean reductions in diastolic blood pressure after 8 weeks of double-blind treatment were significantly greater in each of the ER felodipine treatment groups (2.5, 5, and 10 mg ER felodipine: -7.8, -9.5, and -11.3 mm Hg, respectively) than in the placebo group (-5.3 mm Hg). The effect was dose dependent for both diastolic and systolic blood pressure. Moreover, much of the peak antihypertensive effect was still present at trough, confirming the 24-hour efficacy of the drug. Felodipine was well tolerated.

Resolving a challenge to the therapeutic relationship: a single-case study.

The selection of a case of demonstrated change using a quantitative criterion preceded an exploration of possible change mechanisms in therapy. Between-session variations in the therapeutic relationship revealed by a quantitative measure prompted an intensive qualitative investigation of in-session events. Within these events, the study focused on challenges to the therapeutic relationship and their subsequent resolution. Understanding the resolution of such challenges to the relationship was guided by a rational model derived from the treatment rationale. A tentative account of the process of change is offered, and case replications are required to confirm and extend the findings.

Tender gender issues.

For 40 years, I have been a male on this planet. Nearly half of those years I have proudly worked as a speech-language pathologist. Some say that I don't seem like other men, whatever that means. I am told that I am sensitive, caring, even loving. Why do some believe that women corner those markets? Once I was invited to participate in a men's group, a collection of men from throughout the community who talk about issues that relate to men. What fun, I thought. It wasn't long before I realized that I did not belong in that group. Discussions turned to bashing--women, work, life. The other group members wanted me to continue to participate because they indicated that I represented another side--a happy side. You see, I love my wife. I love my kids, too. What's more, I enjoy my work and sincerely believe that it is important. I value the opportunity to work with student, faculty, and administrative colleagues I respect. I guess my views were not too popular with the men's group.

Lack of synchronized seasonal variation in the intensity of psychological problems.

Temporal variation in the subjective intensity of psychological problems identified by 40 psychotherapy clients (most diagnosed as depressed) was investigated longitudinally. Each client rated the intensity of 10 individualized problems 3 times per week (on Tuesdays, Thursdays, and Sundays) for an average of 6 months. Ratings from all clients were spread over 3 years. When scores were statistically adjusted for client differences and average rate of improvement, no significant variation among months was found, regardless of problem content or client gender. Standard assessment measures administered 4 times to each client also failed to show systematic seasonal variation.
