Research Critique of a Quantitative Research on Nursing Practice


Provision of the best standards of care to clients and patients is what nurses are expected to meet through the provision of the evidence-based practice whenever necessary. A critical part of this process of providing health care on the basis of the best available evidence entails appraisal of primary research. The need for nurses to improve their practice makes it critical for them to apply evidence in order to improve their theoretical and clinical skills and knowledge and be able to assess the quality of the available research relevant to their practice (Wood & Kerr, 2011; Boswell, Boswell & Cannon, 2014).Evidence based practice entails incorporation of professional expertise, patient preference and need, and the best evidence available. Additionally, identification of this “best evidence” calls for the nurses to undertake a critical review and evaluation of the research studies in order to ascertain if the research is useful and of sufficient quality for effective application to their practice.

The title of this research article is very concise and clearly describes the focus of the research itself –“Causal model of health: health-related quality of life in people living with HIV / aids in the northern part of Thailand”. Even though, the approach of the research is not precisely argued, its nature sets out to “examine the causal relationships existing between antiretroviral treatment, age, self-care strategies, symptom experience, social support andhealth related quality of life” in the identified sample and population(Cormack, 2000). These variables are so apparent in the title, though not indicated in the title. The use of the word “causal” is a suggestion that this is a quantitative research article.

The nursing research article has an outline featuring the various aspects its covers in its content has highlighted: an introduction part as described above, a section on protection of human participants, the process and methods of data collection, data management and analysis, interpretation of the findings and the provision of future research, and lastly there is a section of conclusion with a precise summary of the content of the research article (Tangkawanich, Yunibhand, Thanasilp & Magilvy, 2008).

Protection of Human Participants

The participants, which were RN’s, CAN’s and LPN’s in the hospital vowed to commit to confidentiality on the matter in relation to the research undertakings, information gathered and ensuring a professionally reputable ethical standards.However, they were requested to speak frankly about neglecting to undertake routine aspects of their day-to-day responsibilities in front of their peers. Additional validity and privacy was obtained through a multiple questionnaires administered by the researcher with the different participants in the study.

According to Cormack, (2000), the merits accruing from the context of this research article is that a greater ethical considerations were ascertained through seeking approvals of the relevant bodies, incorporated with informed consent on both the part of the authorities and the participants. Even though the study was voluntary, the author didn’t put it clear what information was given to the participants.

Data Collection

The study do not adequately describe the data collection procedures. This would a problem of replication and rigor. The research doesn’t indicate precisely who administered the questionnaires, or even if they were self-report of the participants own convenience and time, or whether there was a researcher at the time of completion (Boswell, Boswell & Cannon, 2014). The research data collection period for this study took one and half years with the variables of consideration categorized as social support, self-care strategies, symptom experience, antiretroviral treatment, age and the HRQL.

However, the study is considered to have applied multiple data collection instruments, described in detailed, and their provenance was accounted for. Theyused the Symptom Experience Questionnaire, the Social Support Questionnaire, the Health Related Quality of Life Questionnaire and the Self-Care Strategies Questionnaire (Cormack, 2000).
