Trial of Problem Solving and Depression Treatment

Subject

Research Critique of “Randomized controlled trial of problem solving treatment, antidepressant medication, and combined treatment for major depression in primary care” As stated by the Royal College of Nursing (1993), nurses should be able to expand their knowledge and skilled to initiate changes in their practice through reviewing and evaluating research studies.  The foundation of nursing is an evidence-based practice that involves finding, critiquing and applying evidences within the field.

Critique research involves a careful examination of all aspects of the research so as to judge its strengths, weaknesses, purpose, and importance (Hek 1996).  The aim of this paper is to critique the study of a randomized controlled trial of problem solving treatment, antidepressant medication, and combined treatment for major depression in primary care.  The reason why I selected the mentioned study is because of its relevance to the filed of psychiatric nursing specifically the treatment of depression.

The current research critique uses the critique tools produced by the Agency for Health Research and Quality (AHRQ).  The critique paper is divided into four sections: its relevance to my topic or question, the conclusions, my confidence in its findings, and how well the findings carry over to the settings I’m interested in.

Introduction

Based on the introduction of the study, the research was conducted to examine whether a combination of problem solving treatment with antidepressant medication is more effective than either treatment alone.  The researchers also studied the effectiveness of problem solving treatment administered by practice nurses in comparison to general practitioners having both trained in the technique.

Its relevance to my topic or question

My research question is related to the treatment of depression and how nurses can take an active role in partner of the patient in his or her recovery.  The PICO framework can be applied to the study with patients who are depressed as the population; the interventions used are problem solving treatment by research general practitioner or research practice nurse or antidepressant medication or a combination of problem solving treatment and antidepressant medication; the comparison between the subjects as groups were measured using Hamilton rating scale for depression, Beck Depression Inventory, clinical interview schedule, and the modified social adjustment schedule assessed at 6, 12, 52 weeks; and, finally, the outcome showed that patients have clear improvement over 12 weeks, the four kinds of treatments were effective, and the effectiveness of the four treatments regardless whether suitably trained practice nurses or general practitioners administered the problem solving or medication treatments.

The abstract of the paper showed the objectives, design, setting, participants, interventions, main outcome measures, results, and conclusions of the study.  The researchers utilized a randomized, controlled trial with four treatment groups namely

  • problem solving treatment given by research general practitioners;
  • problem solving treatment given by research practice nurses;
  • antidepressant medication given by research general practitioners;
  • combined problem solving treatment and antidepressant medication.

The selection of the participants were based on the following criteria: aged 18 to 65 years old, have a depressive disorder that required treatment but not urgent hospital referral, scored 13 or above on the 17-item Hamilton rating scale for depression, and a minimum duration of illness of four weeks.  Some patients were excluded from the study due to the presence of additional psychiatric disorder prior to the onset of depression; were receiving concurrent treatment with antidepressant medication or psychological treatment; had brain damage, learning difficulties, schizophrenia, drug dependence, recent alcohol abuse, or physical illness; have clinical condition inconsistent in the research protocol such as psychotic features or serious suicidal ideation.

As a result, a total of 151 patients met the entry criteria with 144 patients diagnosed to have definite depression while seven patients have probable major depression.  While this is a good sample size, the problem lies with distribution of the sample.  The sample number for patients with probable major depression, specifically, is rather low.  An equal, if not almost equal, sample size with regard to the categories would have supported data analysis, when determining profound differences between the effectivity of various treatment approaches and definite depression diagnosis as opposed to the seven patients who have probable major depression.

The study addresses the issue concerning my research question of the treatment of depression and the role of nurses as a partner of the client and his or her recovery.  The research study can also be applied to other branches of nursing care such as geriatric nursing where the nurse can take an active role in rehabilitation programs provided that nurses are trained on how to conduct and manage the necessary nursing intervention deemed appropriate to the recovery of the patients.

The abstract showed a shorter version of the conclusion that does not explicitly explain the overall findings of the study.   The abstract simply stated the study arrived to a conclusion that problem-solving treatment is an effective treatment for depressive disorders in primary care.  The combination of this treatment with antidepressant drugs is no more effective than either treatment alone.

The conclusion page, however, explained in detail how appropriately trained nurses can actively participate in the administration of the problem solving treatment given to patients.  It also stated that the problem-solving treatment is a goal oriented, collaborative, and active process and focuses on the present.  This process enables patients to gain a clear sense of involvement in the recovery process.

The conclusion also offered a recommendation that the treatment for depression is suitable for primary care because it’s relatively brief and can be given by primary care nurses.  Lastly, the conclusion page stated recommendations for future studies specifically the first challenge for the future is to provide training for interested practice nurses in delivering the treatment as evaluated; and a need to evaluate a briefer adaptation of problem solving techniques can be used by general practitioners in their regular consultation.

The study results showed tables and figures as data gathered from the groups of participants.  The conclusion were fairly in favor of the recovery of patients who belonged to the groups of problem solving by general practitioner, problem solving by nurse, and the combination of problem solving and medication treatment.  It does not, however, reflect the decline or drop of the percentage of patients who recovered.  Based on the table, it showed a drop of 4% of the number of patients who recovered on the 12th week and the 52nd week.

The review of related literature showed an accurate basis of the study.  The literature review supports the study mainly because of studies such as problem solving treatment in primary care has been shown to be effective for major depression; the treatment has been shown to be effective when given by general practitioners; and that community nurses can be trained in problem solving techniques.  The research study confirmed that nurses can be trained to administer problem solving techniques.  Furthermore, the literature review also supports the purpose of problem solving treatment as a therapy to treat major depression.

The results compares to other studies in the sense that it affirms that nurses can be trained to provide psychological treatments successfully.  In primary care, nurses have used behavioral methods to treat obsessional and phobic patients (Ginsberg et al. 1984).  Nurses have also been used in primary care to try to improve compliance with antidepressant medication (Wilkinson et al. 1993).  In hospitals, nurses also have been trained to incorporate problem-solving techniques in the counseling of patients after intentional self-harm (Hawton and Kirk 1989; Salkovskis et al. 1990).  Thus, the quantitative study of the treatment of depression is supported by other studies.

The researchers chose to focus on the four treatment groups to determine whether there is any difference on the rate of effectiveness whether it is anti-depressant medications alone, solely problem solving treatment given by general practitioners, problem solving treatment given by nurses, or a combination of problem solving treatment and anti-depressant medication.

My confidence in its findings in the methods section

My confidence on the findings of the study is mainly on the large sample size, randomized and controlled manipulation of the subject groups, and characterized by PICO or patient, intervention, comparison and outcomes framework.  Additionally, the methods section should have five principal elements that influence the quality of the findings namely the completeness of the model analyzed, the quality of the measures or methods, the quality of the data, the ability to control the differences between groups being compared, and the appropriateness of the statistical analyses.

The model analyzed pertains to the description of the dependent variable and independent variable.  The independent variable of the study is the primary care of nurses and general practitioner while the dependent variable is the effectiveness of the treatment for depression.  The relationship of the independent variable and the dependent variable correlates to the outcome of the study.  Thus, the more efficient and well-trained the nurses and general practitioner are in the context of primary care then there is a higher rate of effectiveness of a particular treatment, among the four types, for depression.  The study left out important variables such as the background and experience of the nurses and general practitioners and whether the same primary caregivers were rendered the treatment during the course of the 52-week study.

The study made use of the two most common tools to assess depression amongst adolescents and adults namely the Hamilton Depression Rating Scale (HDRS) as the main outcome measure and the Beck’s Depression Inventory (BDI-II).   The statistical analyses were based on the BDI II and HDRS data.  The BDI-II is a self-report measure while the HDRS serves as an assessment used by therapists in clinical interviews to resolve the severity of depression in adults.  The Hamilton Depression Inventory is composed of 38 questions design to determine 23 items linked with symptoms of depression (Reynolds & Kobak 1995).

Participants answered on a rating scale of zero to four.  This assessment, commonly used in clinical research and practice, is doubted in terms of its standardization of scoring criteria and administration.  On the other hand, the Beck Depression Inventory II assesses 21 items connected with symptoms of depression on a four-point scale of zero to three (Osman, Kopper & Barrios 2004).  BDI II is a widely used assessment tool that has been updated in order to keep up with latest diagnostic criteria for depression based on the DSM-IV.  It has been, however, questioned due to its reliability and validity in measuring depression in such individuals.

The location of test administration and the working relationship of the primary caregivers and patients can influence the data gathered.  There is a greater likelihood that participants are biased on giving the expected positive responses to the tests given.  It is because of the fact that the people who gathered data are their primary caregivers.  The participants were not blinded to the purpose of the study hence promotes bias to the study.

There were four groups of subjects studied in the research.  There are different from each other.  The first group was given problem solving intervention by general practitioners, second group was given the same intervention but given by trained nurses, third group was medications only, and the fourth group was a combination of the problem solving technique and medications.  Thus, the study has a wider range of control made possible by the four different groups to differentiate and compare the rate of effectiveness on the choice of treatment per group.   The only drawback observed in the study is the time series aspect where it is expected that a higher rate of morbidity of participants can happen.  It means there is a higher possibility that participants might withdraw from the research given its long duration of 52 weeks.

The study observed a randomization to minimize the differences between the groups being compared.  The sample size is sufficiently large to provide a wider scope for comparison on their responses to treatments given to them, respectively.

The paper imparts a meaningful conclusion to further support other studies on how primary caregivers specifically nurses can participate in giving psychological treatments successfully.  It provides a higher level of nursing care in a collaborative care when in partnership with the patient towards his or her recovery.

 The research study was completed at 2000 at Warneford Hospital based in Oxford, Southeast England.  The time or the course of the study was done on a course of 52 weeks.  The treatment was usually given in the patient’s home or local health centre.

The circumstances involved in the study such as the year, location, duration of the study, selection criteria of subjects, and setting of the treatment (home or local health center) may be different in another cities in United Kingdom.  Other health centers may not have as many willing participants as compared to the research study being criticized. The severity of depression also play a significant role to its treatment and how effectiveness of treatment given to the patient.  Furthermore, some local health centers may not have adequate number of trained nurses who can render psychological interventions.

The limitations section is not found in the research paper.  An implication of limitations of the study was integrated in the conclusion section.  The researchers proposed that future studies should be made on evaluation of problem solving techniques used by general practitioners in their regular consultations as well as to provide training for interested practice nurses in delivering treatment for depression.  While these points can be further researched in the future, the study failed to specify limitations such as a lack of homogenous sample groups such as severity of depression, consistent number of participants who completed the 52 weeks duration of the study, and the qualifications and experiences of the general practitioners and trained nurses.

Conclusion

The research paper provides an affirmation that primary care of nurse can be geared to the administration of psychological interventions.  One of the outcomes of the study is that nurses can effectively render an active and positive role in a collaborative goal with patients towards recovery.  Furthermore, the evidences from the research paper showed that depression could be effectively given through a combination of problem solving treatment and anti depressant medications.  It further proved that the treatment of depression is unsuccessful when anti depressant medication is given without any problem solving treatment.
