Literature Review
The biopsychosocial perspective was proposed by the
physician George Engle in 1988 as an alternative to the traditional biomedical
model for the analysis of health behavior. Engle argued that the traditional
biomedical model was too reductionist, and was not capable of accounting for
all the variables that influence health
Developed by the social psychologist Albert Bandura,
selfefficacy is a psychological concept defined as a personal judgement about
the capability of the self to innately achieve set goals (Bandura, 1977). Selfefficacy was first
approached in 1977 in Bandura’s journal article “selfefficacy” from a
psychosocial perspective. Bandura argued that selfefficacy is attained mainly
through three things: (1) what we attempt to perform, (2) what we observe
others doing, (3) how we are persuaded
Knowledge Gap
Since selfefficacy is being analyzed through the
biopsychosocial model, it is a good fit to measure the relationship of
different biological, psychological, and social variables with selfefficacy.
In order to approach the knowledge gap, the predictor variables of confidence,
usefulness, male dominance, and teacher attitude and perception will be
compared statistically with selfefficacy in order to explore correlational
outcomes.
Statistical Requirements
Factorial analysis of variance (ANOVA)
which compares means of two or more independent variables is usually the
utilized statistical tool in experimental design. However, it can also be used
in correlational research
Regression
analysis is another statistical tool that enables the researcher to explore the
relationships among multiple variables, where they examine the influence of the
predictor variables on the outcome variable. There are several types of
regression analyses, the most basic form is simple regression, it’s when
there’s one predictive variable and it’s called a simple regression, and
represented by a correlation coefficient denoted by r^{2}

Discussion
After performing simple
regression analysis for the categorical predictor variables, which are age,
math scores, and science scores; we also performed a multiple regression
analysis for continuous predictor variables, which are confidence, usefulness,
male dominated field, and teacher attitude and perception. We were able to
establish a statistically significant negative correlation between confidence
and selfefficacy. However, the rest of the predictor variables were not able
to establish a correlational relationship with selfefficacy, since all of
their P values were greater than 0.05, hence lacking in statistical
significance
This negative correlation
between confidence and selfefficacy is in accordance with the literature on
selfesteem. Selfesteem and confidence are positively correlated, since both
are defined by feelings of selfworth
