Psychology Article Review on Research Methods

Research Methods

This paper seeks to identify and analyze two articles on quantitative and qualitative methods adopted to examine the relationship between stress and marital satisfaction. “Stress and Marital Satisfaction of Parents With Children With Disabilities in Hong Kong” by Ki & Joanne (2014) shows a quantitative approach to the topic, whereas a study by Laabs (2016), titled “Married to Nursing School: How Stress Affects Marital Satisfaction of Nursing Students”, looks at the issue from a qualitative perspective.

Summary of Research Question, Hypothesis, Research Methods, and Overall Findings

The research questions in the study by Ki & Joanne (2014) revolved around the sources of stress and the way they are associated with the marital satisfaction of parents of children with disabilities. The main hypothesis was that there is a negative correlation between marital satisfaction and parenting stress, especially for those in this category. A total of 72 participants were chosen, of which 55 were female, and 17 were male. Eighty questionnaires were issued to them either by mail or in person. The findings of the study suggested that the alleviation of stressful factors such as time allocation and increasing shared childcare responsibilities are critical to enhancing marital satisfaction.

In the study by Laabs (2016), the queries focused on the actual experiences of married nursing students in the course of a semester and the impact of school stress on marital satisfaction. The study hypothesized that the nursing curriculum was taxing, and that it may  carry over into marriage, thereby affecting marital satisfaction. Seven participants took part in the study with prior consent making journal notes of the experiences they have had from nursing and marital satisfaction perspectives. The overall finding of the study was that nursing school and the stress accompanying it affect marital satisfaction.

Comparison of Research Methodologies

Ki & Joanne (2014) used the quantitative research design in which 72 participants completed a survey. On the contrary, Laabs (2016) adopted the qualitative research design, where seven participants gave their feedback by completing journals. The two research methodologies are different, given the number of respondents. Ki & Joanne’s (2014) method had a higher number of respondents compared to that of Laabs’ (2016) study. Moreover, the qualitative design tends to explore causality whereas the quantitative design merely suggests it (Tuli, 2011).

Sample and Sample Size

Ki & Joanne (2014) studied parents of children with disabilities, with the final list consisting of 72 participants of which 55 were female, and 17 were male. Conversely, Laabs’ (2016) study sample consisted of volunteer married nursing students. The participants were seven in number, comprising six women and one man.

Data Collection Process

Ki & Joanne (2014) collected data from the questionnaires filled by the 72 participants. Laabs (2016) compiled the data from journal notes kept by the respondents. The quantitative method used questionnaires, though the question of whether the participation was voluntary is not clarified. In the qualitative study, participants willingly made journal entries.

Data Analysis

For data analysis, Ki & Joanne (2014) used the IBM SPSS Version 21 that allowed the collection of reports of correlational analyses as well as descriptive statistics. In the Laabs (2016) study, no specific method was used in the analysis of data. The scrutiny focused on four themes: familial social role changes, the imbalances between the family and the nursing school, spousal support, and emotional stress. The collection and analysis of data were carried out by means of established measures in interpretive phenomenological studies, in an anonymous manner. Statistics was obviously used more in the quantitative study by Ki & Joanne (2014).

Differences Between Quantitative and Qualitative Research

From the two articles, the main differences between quantitative and qualitative research are evident. To begin with, qualitative research has a lower number of respondents, while quantitative research makes use of a much higher number. Another notable dissimilarity is that qualitative research tends to explore causality whereas quantitative research suggests it. Moreover, it is evident that qualitative research is more focused geographically, while quantitative research is geographically dispersed (Tuli, 2011).
