A Dimensional Approach to Assess Emotional Wellness: Reliability and Validity of a Modified Emotional Wellness Scale (EWS)

ABSTRACT: The study aims to adapt and validate a measurement tool for emotional wellness, specifically focusing on
its multidimensional structure. The study was conducted by using online survey method with a sample size 356
white-collar employees from selected service sectors in Ethiopia. Primary data was gathered using a modified 16-
item structured emotional wellness questionnaire. Exploratory Factor analysis (EFA) and confirmatory factor
analysis (CFA) was conducted to test the validity of EWS. Cronbach alpha and item-total score correlation was used
to analyse the reliability of the EWS. The EFA showed that the EWS has a two-factor structure, with 14 items
accounting for 52.2% of the total variance, indicating a valid factor structure. The sub-dimensions were identified as
"Emotional Management" and "Emotional Awareness,". Confirmatory Factor Analysis (CFA) supports the twofactor model, with excellent fit with various statistical indices (CIMN (X²/ df=1.86), RMSEA =0.052, SRMR =
0.049, CFI= 1.000, NFI= .996, GFI =.997 and RFI= .995). The scale's reliability is confirmed through the
Cronbach Alpha internal consistency coefficient, with an overall score of α= 0.922 and with sub-dimensions scoring
α= 0.897 and α= 0.864, respectively. The scale's unique features demonstrate high discriminatory power, with a
satisfactory correlation with the items' index score and a range of 0.527 to 0.723. The finding shows that the EWS is
a reliable and theoretically sound tool for assessing emotional wellness. This measurement instrument has been
exclusively evaluated on white-collar employees within select service sectors in Ethiopia. It requires further testing
across diverse cultures, sectors, and larger sample sizes to ensure generalisability.

Enhancing Long-and-Short-Term Forecasting for Optimized Microgrid Energy Management Through Advance Hybrid Deep Learning Models
1 Kayode Owa, 2 Charles Akinropo
DOI: https://doi.org/10.56293/IJASR.2025.6302
ABSTRACT: Solar power, while abundant, is unpredictable due to its intermittency, causing instability in energy supply
and imbalances between supply and demand, which can threaten grid reliability. To address these challenges,
innovative solutions are required, especially as electricity demand fluctuates. Energy Storage Systems (ESS) help
manage peak shaving and load shifting, but erratic energy sources can degrade batteries, leading to high costs.
Accurate forecasts of energy consumption (EC) and solar energy generation (EG) are crucial for optimizing solar
microgrids. This study evaluates deep learning models, including Convolutional Neural Networks (CNN), Gated
Recurrent Units (GRU), and a hybrid CNN-GRU model, to predict both EC and EG. A multi-input, parallel
processing approach was used to capture temporal and spatial patterns for real-time applications with reduced data
drift and improved accuracy. The model was tested using 47 months of historical data from the Sceaux microgrid
near Paris, France, spanning from December 2006 to November 2010, from the University of California, Irvine
repository. The data was also used to optimize the photovoltaic (PV) system sizing. The proposed method achieved
excellent results for EG prediction with a Mean Absolute Error (MAE) of 3.974 and a Root Mean Squared Error
(RMSE) of 6.603. For EC prediction, it obtained an MAE of 4.869, an RMSE of 6.527, and a Mean Absolute
Percentage Error (MAPE) of 0.113, demonstrating its effectiveness for both short-term and long-term forecasting.
