What is the SWLS used for?

The satisfaction with life scale is a valuable instrument for academic research in social and medical areas and various disciplines. It has shown a high degree of reliability in multiple studies, an appropriate internal consistency between items, correlations between elements, and adequate validity.
Life satisfaction can be explicitly assessed in one life domain (work or family) or as a global measure of life satisfaction. The Satisfaction with Scale SWLS total score is helpful for group comparisons in research or program evaluation.
It is a good tool for clinical purposes to understand which areas of life are important to the individual and the basis for the assessment. Generally, the questions that make up the satisfaction with scale are open to interpretation, making this scale suitable for adults with different backgrounds.

Steps to Apply the Life Satisfaction Scale

Now that you know what the Life Satisfaction Scale (SWLS) is and what its main uses are, we will share the main steps to apply it in research:

1. Selection of Sampling Method

The first step is to choose the sampling method through which the total and the characteristics of the population studied obtain. If you don’t know how to calculate your sample size correctly, check out our free sample calculator.

2. Adaptation of the Instrument

The next step consists of the adaptation of the satisfaction with life scale (SWLS), which may include the translation of the items from English to Spanish, the evaluation of the conceptual equivalence between both, and a work of cultural adaptation that allows making sure that the instrument is clear and understandable to all participants.

3. Application of the Instrument

Once it verifies that the participants understand and comprehend the items. The field research phase continues, which implies the application of the SWLS in the total sample, either individually or in groups.
As previously mentioned, the response options generally range from 1 (totally disagree) to 7 (totally agree), with a minimum total score of 7 (low satisfaction) and a maximum of 35 (high satisfaction).
Before starting this data collection phase. Thus, It is essential to have the signed consent of all the participants and organizations involved in the research.

4. Data Analysis

Finally, the statistical data analysis process is carries out, including descriptive analysis. Analysis of the validity of the internal structure of the SWLS and reliability analysis.
Other tests that can apply to guarantee the reliability of the results are the sample adequacy and the Bartlett sphericity test.

Technological tools to apply the SWLS

Various technological tools apply the satisfaction with life scale (SWLS) effectively and practically, reducing the risk of losing necessary documentation for reasons unrelated to the research.
An example of this is the Questioner platform for online surveys and offline surveys. which has the option of generating questionnaires with a Likert scale and facilitates fieldwork for both researchers and participants.
