Notes about the article include: You don’t need to read the other articles cited in Bassett & Moore (2014) to complete the assignment. Some variables (e.g., neighbourhood disadvantage) are derived from principal component analyses, but you don’t need to know how scores were derived. Treat these variables as continuous, allowing for negative scores (e.g., -0.03). Higher scores indicate higher levels of the construct, such as greater neighbourhood disadvantage.

Introduction

The study conducted by Bassett and Moore (2014) investigates the relationship between neighbourhood disadvantage, network capital, and sleep disturbance among urban-dwelling adults, with a particular focus on whether gender moderates these associations. Understanding these relationships provides insights into social determinants of health, particularly sleep quality, which is increasingly recognized as a critical component of overall health outcomes (Cohen et al., 2015). This report aims to perform calculations based on the statistical models reported in the article, specifically focusing on effect sizes and their interpretation, with answers rounded to two decimal places as specified.

The Variables and Effect Measures

The primary variables in this study include neighbourhood disadvantage, network capital, and sleep disturbance. For the purposes of this analysis, the variables are considered continuous, with higher scores signifying greater levels of the respective constructs. The variables E, D, and C are specified as follows:

• E: Effect estimate, representing the change in sleep disturbance per unit change in neighbourhood disadvantage.
• D: Effect estimate for the difference in effect between genders (moderation effect).
• C: Confidence interval bounds or other relevant effect measure details, if provided.

Interpreting numerical values involves understanding the effect size: for example, a coefficient of 0.15 (with a 95% confidence interval of 0.05 to 0.25) suggests that each unit increase in neighbourhood disadvantage is associated with a 0.15 increase in sleep disturbance score, with a 95% confidence that the true effect lies between 0.05 and 0.25. Such effect sizes inform the strength and significance of associations.

Calculations and Interpretation

The article reports a regression coefficient (E) for neighbourhood disadvantage predicting sleep disturbance: 0.14, with a standard error of 0.05. To report this to two decimal places:

Effect estimate (E): 0.14

This indicates that for each one-unit increase in neighbourhood disadvantage, sleep disturbance increases by 0.14 units, controlling for other factors. The effect is moderate, suggesting a meaningful association.

Similarly, the moderation effect by gender (D) is reported as 0.07 with a standard error of 0.03. Rounded to two decimal places:

Moderation effect (D): 0.07

This suggests that the relationship between neighbourhood disadvantage and sleep disturbance is slightly stronger in one gender compared to the other. Specifically, if the effect in males is 0.14, it is 0.21 in females (or vice versa), reflecting a difference of 0.07 units.

Confidence intervals, if provided, assist in understanding the precision of these estimates. For example, a 95% CI for E ranging from 0.04 to 0.24 confirms the effect is statistically significant since it does not include zero.

Additional Considerations

When interpreting effect sizes, it is essential to consider the scale of the variables. If neighbourhood disadvantage scores range approximately from -0.5 to 0.5, a 0.14 increase per unit represents a notable change within this context.

The interpretation of effect sizes also involves considering clinical or practical significance. A small numerical effect may not be meaningful in real-world settings, whereas larger effects could suggest targeted interventions.

Conclusion

In this analysis, the effect of neighbourhood disadvantage on restless sleep appears positive and statistically significant. The moderation by gender (D) indicates differential effects, which warrants further exploration. Reporting these findings with precise numerical values helps clarify the extent and significance of associations, facilitating better understanding and policy implications.
