Abstract
This study had three distinct objectives. First, to examine the
relationships between perfectionism and loneliness to depressive
symptoms. Second, to identify perfectionism and loneliness as unique
predictors of depressive symptoms. Third, to examine whether perfectionism
and loneliness interact to predict depressive symptoms. Results
suggest that the three dimensions of perfectionism measured by the
Multidimensional Perfectionism Scale (Hewitt & Flett 1991b)
are significantly correlated with one another. In addition, loneliness
was found to be correlated with depressive symptoms. Surprisingly,
none of the dimensions of perfectionism were significantly correlated
with depressive symptoms. Overall, perfectionism was found to be
neither a significant main nor interactive predictor of depressive
symptoms, while loneliness was found to be a significant unique
main, but not interactive, predictor of depressive symptoms.
Introduction
In past research, perfectionism and loneliness have both been linked
to maladaptive behaviors and depressive symptoms. However, few studies
have examined these variables as either main or interactive predictors
of depressive symptoms. By examining these variables simultaneously,
it is possible to determine their relative explanatory power in
accounting for depressive symptoms.
Perfectionism
Perfectionism has increasingly been studied as a multidimensional
personality trait over the last decade. Varying concepts of perfectionism
have been proposed, most often regarding perfectionism as a maladaptive
trait (Blatt 1995). These notions of perfectionism rise from the
idea that it may stem from neurotic behavior. Research, using a
variety of perfectionism measures, provides support for this claim:
Perfectionism has been associated with depressive symptoms (Chang
and Sanna 2001; Enns and Cox 1999; Hewitt and Flett 1991a 1993;
Joiner and Schmidt 1995; Lynd-Stevenson and Hearne 1999), greater
negative affectivity (one’s emotional state) and less positive
affectivity (Chang 2000; Frost et al. 1993), low self-efficacy
(Hart et al. 1998), increased suicidal ideation (Hamilton
and Schweitzer 2000; Hewitt et al. 1994; Hewitt et al.
1997), and greater social anxiety (Juster et al. 1996;
Saboonchi et al. 1999). Others have suggested perfectionism
can be “normal” rather than “neurotic,”
a distinction made by Hamachek (1978), who suggests that individuals
can be “satisfied” (Slade 1982) with their performance
and engage in “positive striving” (Frost et al.
1993) accompanied by positive effect and increased self-esteem.
Two multidimensional measures of perfectionism are predominant in
the current literature (Frost et al. 1990; Hewitt and Flett
1991). These measures have been developed from numerous studies
of clinical populations, which indicate perfectionism is widely
associated with numerous psychopathologies (Terry-Short et al.
1995) and maladaptive behaviors, as indicated above. Hewitt and
Flett’s (1991a) Multidimensional Perfectionism Scale (MPS)
assesses perfectionism as a phenomenon consisting of three dimensions:
self-oriented, other-oriented, and socially-prescribed perfectionism.
Self-oriented perfectionism is defined as the tendency
for an individual to set and seek high self-standards of performance.
Other-oriented perfectionism describes the tendency for
an individual to expect that others should or will be perfect in
their performance, and socially prescribed perfectionism
refers to the tendency for an individual to believe that others
expect perfection from him or her (Hewitt and Flett 1991b).
The
second predominant multidimensional perfectionism measure is the
Frost Multidimensional Perfectionism Scale (FMPS) (Frost et al. 1990). Frost et al. define perfectionism as a
variable involving excessive self-criticism associated with higher
personal standards, concern over meeting social expectations, and
excessive focus on organization and neatness, and doubts about the
effectiveness of one’s actions.
Perfectionism:
Link to Negative Outcomes, Including Depressive Symptoms
In
the Diagnostic and Statistical Manual of Mental Disorders 4th
edition (American Psychiatric Association 1994), major depression
is defined by depressed mood, markedly diminished interest or pleasure,
significant weight loss or gain, insomnia or hypersomnia, psychomotor
agitation, fatigue, feelings of worthlessness or guilt, diminished
ability to think or concentrate, and recurrent thoughts of death.
Depressive symptoms can be experienced in varying degrees, ranging
from mild responses to negative life experiences, to severe, disabling,
and persistent distortions of one’s internal and external
world. Depressive symptoms are complex, and many believe that depression
results from severe disruptions in one’s interpersonal relations
or from serious threats to one’s self-esteem and feelings
of self worth.
Numerous
studies using the MPS point to a positive correlation between depressive
symptoms and levels of perfectionism (Hill et al. 1997;
Lynd-Stevenson and Hearne 1999). In addition, the FMPS has also
demonstrated significant correlations between perfectionism and
depressive symptoms (Enns and Cox 1999; Frost et al. 1993). Perfectionism
may also interfere with treating those suffering from clinical depression;
findings indicate perfectionism hinders the successful treatment
of depressive symptoms (Blatt et al. 1995; Blatt et al. 1998), regardless
of the method of therapy used. These modalities include cognitive
therapy, interpersonal psychotherapy, and varieties of drug treatment.
The
three different domains of perfectionism, as measured by the MPS,
are differentially related as potential correlates of depressive
symptoms, which are often measured by the Beck Depression Inventory
(BDI) (Beck et al. 1961). The strongest association is usually found
between socially prescribed perfectionism and depressive symptoms
(Enns and Cox 1999; Flett et al. 1991; Hewitt and Flett 1991a; Hewitt
et al. 1996; Wyatt and Gilbert 1998), although consistent correlations
between depressive symptoms and self-oriented perfectionism are
frequently found as well. Individuals with socially prescribed perfectionism
perceive that external sources impose standards upon them. These
perfectionist individuals believe they must maintain unrealistic
expectations that others have placed on them, and these are necessary
for acceptance and approval (Frost et al. 1990; Hewitt and Flett
1991a, 1991b). These stressors appear to be out of the individual’s
control, causing a sense of failure, and potentially depressive
symptoms.
Self-oriented perfectionism is also associated with depressive symptoms.
Like socially prescribed perfectionism, self-oriented perfectionism
places an emphasis on the individual and his or her achievements.
Studies by Hewitt and Flett (1991a) indicate excessive self-criticism,
unrealistic expectations, and feelings of worthlessness can lead
to depressive symptoms or dysphoria, a condition of persistent depressive
feelings. In a 1993 study of 51 unipolar depressed patients and
94 mixed psychiatric patients, Hewitt and Flett also found self-oriented
perfectionism predicts depressive symptoms in an achievement-stress
context, and the stressor affects the relationship between the depression
and the specific type of perfectionism. Furthermore, a second study
of 121 patients with either unipolar or bipolar depression indicated
self-oriented perfectionism interacts with achievement stress. Hewitt
and Flett determined that specific achievement stressors are necessary
for self-oriented perfectionism to manifest itself as depression
(1996). Both self-oriented and socially prescribed perfectionism
are related to psychological distress in both clinical and non-clinical
populations. In contrast, other-oriented perfectionism is sometimes
associated with fewer symptoms of depression (Flett et al. 1995),
raising the question of how closely other-oriented perfectionism
defines the original construct.
The relationship between perfectionism and depressive symptoms has
implications for treating maladaptive forms of perfectionism that
might contribute to an individual’s depressive state. This
study identifies whether perfectionism can serve as a unique main
or interactive predictor of depressive symptoms in conjunction with
loneliness, and if combating perfectionist tendencies may therefore
alleviate these depressive symptoms.
Loneliness
The debilitating emotions present in those suffering from depressive
symptoms are also often found in the experience of loneliness. Loneliness
is widely agreed to result from a deficiency in an individual’s
social relationships. Additionally, loneliness is subjective, and
does not reflect the size of one’s social network or their
number of associates. Lastly, loneliness is painful and distressing
(Peplau and Perlman 1982). Similar to findings for perfectionism,
loneliness has been correlated with numerous maladaptive characteristics
and negative behavior states including depressive symptoms, suicide,
hostility, alcoholism, psychosomatic illnesses, and a poor self-concept
(Rokach et al. 2002; McWhirter 1990). Research has focused on studies
of personality traits common in lonely people, finding they tend
to express attributes of shyness, low levels of assertiveness, and
introversion (Bell 1985; Hojat 1982; Jones et al. 1981) in addition
to the above-mentioned symptoms and illnesses. Several researchers
have attempted to develop measures of loneliness. The University
of California, Los Angeles (UCLA) Loneliness Scale (Russell et al.
1980), and its revised version, are widely used measures of individuals’
levels of loneliness.
Loneliness:
Link to Negative Outcomes, Including Depressive Symptoms
Empirical
data suggests that loneliness is significantly correlated to depressive
symptoms (Bradley 1970; Bragg 1979; Hsu et al. 1987) and numerous
other negative outcomes. Lonely people have indicated they are less
happy, less satisfied, more pessimistic, and suffer from more depressive
symptoms (Peplau and Perlman 1982) than people who are not lonely.
Lonely individuals have also reported negative behaviors and affective
states when experiencing loneliness, including tenseness, restlessness,
and boredom. Other studies have indicated that loneliness is also
linked to high scores on pessimism, and is negatively correlated
with happiness and life-satisfaction (Rokach et al. 2002).
Additional
associations between loneliness and depressive symptoms were found
in Hsu et al.’s (1987) study of the cultural and emotional
components of these two conditions. Findings indicated that depressed
clients scored significantly higher on the UCLA Loneliness Scale
than non-depressed foreign, American, and Chinese students, indicating
a strong relationship between depression and loneliness, regardless
of one’s nationality. Depressed individuals also scored significantly
higher than both American and Chinese students on Loneliness Anxiety,
and Loneliness Depression, subscales of the Belcher Extended Loneliness
Scale.
The
present study had three distinct purposes. First, it set out to
examine the relations of perfectionism and loneliness to depressive
symptoms. Second, to examine the associations between perfectionism
and loneliness as unique predictors of depressive symptoms. Lastly,
it would determine if perfectionism and loneliness interacted to
predict depressive symptoms.
Previous research indicates that self-oriented and socially prescribed
perfectionism are positively correlated with depressive symptoms.
We predicted a consistent result in the current study. In addition,
we predicted loneliness would be positively correlated with depressive
symptoms. Since measures of perfectionism and loneliness are distinctly
different, we expected that both perfectionism and loneliness would
be unique predictors of depressive symptoms. Finally, we expected
perfectionism and loneliness would interact to predict depressive
symptoms. For example, we expected individuals with high levels
of socially prescribed perfectionism and high levels of loneliness
to report the greatest number of depressive symptoms.
Few studies have compared loneliness and perfectionism against one
another as predictors of depressed symptoms. As expected, unique
predictors of depressive symptoms, perfectionism and loneliness
have both been associated with many maladaptive behaviors and emotional
states. This study empirically tests the correlations between loneliness,
perfectionism, and depressive symptoms.
Materials
and Methods
Eighty-nine
college students (25 male and 64 female) were recruited from a large
Midwestern university. All participants were enrolled in an upper-division
psychology course and obtained extra course credit for participating.
Most of the participants indicated they were Caucasian American
(68.7%), followed by African American (13.1%), Asian American (9.1%),
Latin American (2.0%), and then Other. Ages ranged from 18 to 30
years (M = 19.6, SD =1.6). Men and women were
not found to differ significantly in age.
All three types of perfectionism and loneliness were included as
predictors of depressive symptoms in a simultaneous regression analysis.
It was expected that loneliness, socially prescribed, and self-oriented
perfectionism would emerge as main predictors of perfectionism as
they have in the past. A second regression analysis was also run,
involving the main factors included in the first regression (self-oriented
perfectionism, socially prescribed perfectionism, other-oriented
perfectionism, and loneliness), as well as additional interactive
terms between loneliness and the three dimensions of perfectionism.
Measures
Depression:
The Beck Depression Inventory (Beck et al. 1961) is a 21-item scale
used to measure the intensity of depressive symptoms. Scores on
each item can range across a four-point scale, for example, 0 =
“I do not feel sad,” to 3 = “I am so sad or unhappy
that I can’t stand it.” The total inventory score ranges
from 0 to 63.
Perfectionism:
The MPS is a 45-item measure of perfectionism consisting of three
dimensions: Self-Oriented Perfectionism (SOP; e.g., “One
of my goals is to be perfect in everything I do.”), Other-Oriented
Perfectionism (OOP; e.g., “If I ask someone to do
something, I expect it to be done flawlessly.”), and Socially
Prescribed Perfectionism (SPP; e.g., The people around
me expect me to succeed at everything I do.”). The MPS yields
three separate scores for each dimension of perfectionism. Each
statement is measured on a seven-point Likert-type scale, from 1
(strongly disagree) to 7 (strongly agree).
Loneliness:
The 20-item UCLA Loneliness Scale consists of self-relevant statements
that respondents answer on a four-point scale, from 1 (not at all)
to 4 (frequently). Half of the item measures are worded to indicate
a high level of loneliness, while the other half is worded in the
opposite direction, requiring these to be reverse scored. Each participant’s
scores are averaged across the 20 items, so scores range from 1
(low loneliness) to 4 (high loneliness).
Procedure:
All study measures were administered to participants in the form
of a take-home survey that was to be returned the next day of class.
Of the initial sample of 100, 11 participants failed to complete
all measures, and thus their responses were not analyzed. This left
a total of 89 completed responses that were available for subsequent
analysis. Participants were not made aware of the purpose of the
study until after the study was completed. To protect the participants’
anonymity, only participant numbers were placed on the instruments.
Results
Means, standard
deviations, and alpha internal consistency coefficients (which indicate
the reliability of the measures used) for all variables are presented
in Table 1, which also presents zero-order correlations between
all measures. Results indicated the three measures of perfectionism,
self-oriented, socially prescribed, and other-oriented perfectionism,
were highly inter-correlated with one another. A significant positive
correlation was found between SOP and OOP, r (correlation)
= 0.56, p (observed significance level) = <0.01. Data
analysis also indicated a positive correlation between SOP and SPP,
r = 0.44, p = <0.01, and between OOP and SPP,
r = 0.48, p = <0.01. All three measures of
perfectionism also exhibited high internal consistency (SOP ? =
0.92, OOP ? = 0.81, SPP ? = 0.78).

As Table 1
shows, none of the three MPS perfectionism dimensions were found
to have significant correlations with depressive symptoms. An insignificant
negative correlation emerged between SOP and BDI, = -0.19, ns
(non-significant). Likewise, correlates of OOP and BDI emerged as
non-significant, r = 0.01, ns, as did correlates
between SPP and BDI, r = 0.01, ns. Only a single
significant correlation emerged, loneliness and socially prescribed
perfectionism, r = 0.24, p = <0.05. As hypothesized,
loneliness was also correlated with depressive symptoms, r
= 0.57, p = <0. 01. Loneliness also accounted for 31%
of the variance in depressive symptoms (r2 =
0.31). It was surprising, however, that none of the measures of
perfectionism were significantly correlated with depressive symptoms.
These findings stand contrary to past findings of a positive correlation
between the socially prescribed and self-oriented dimensions on
Hewitt and Flett’s MPS.
In
the first regression analysis, only loneliness emerged as a main
unique predictor of depressive symptoms, t (84) = 6.30,
p = <0.001. The second regression analysis was consistent
with the previous regression results, and only loneliness, as measured
by the UCLA Loneliness Scale, emerged as a significant main unique
predictor of depression, t (84) = 3.57, p = <0.001
(Table 2). Loneliness did not interact with any of the assessed
perfectionism variables as a significant predictor of depressive
symptoms. However, the interaction between self-oriented perfectionism
and loneliness was nearing significance levels (t (81)
= 1.90, p = 0.061).

Discussion
Results were
surprisingly inconsistent with expectations for positive correlations
between depressive symptoms with socially prescribed perfectionism
and with self-oriented perfectionism based on previous studies (Chang
and Sanna 2001; Enns and Cox 1999; Hewitt and Flett 1991a, 1993).
Earlier research also indicates numerous correlations between greater
negative affectivity and perfectionism (Chang 2000; Frost et al.
1993), low self-efficacy and perfectionism (Hart et al. 1998), and
increased suicidal ideation and perfectionism (Hamilton and Schweitzer
2000; Hewitt et al. 1994; Hewitt et al. 1997). This research provides
support that some of the dimensions of perfectionism should be significantly
and positively correlated with depressive symptoms. Zero-order correlations
and a regression analysis indicated that although the Hewitt and
Flett MPS, Beck Depression Inventory, and UCLA Loneliness Scale
were internally consistent and the measures of perfectionism were
significantly correlated with one another, none of these three perfectionism
dimensions was predictive of depressive symptoms.
The strong correlation between scores on the UCLA Loneliness Scale
and the Beck Depression Inventory reaffirms previous findings of
positive correlations between loneliness and depressive symptoms
(Bradley 1970; Bragg 1979; Hsu et al. 1987). These findings suggest
that future studies of depressive symptoms with negative affective
conditions should consider loneliness as a robust predictor of these
maladaptive emotional and behavioral conditions.
The
interactive effects of self-oriented, socially prescribed, and other-oriented
perfectionism with loneliness did not appear as significant main
or interactive predictors of depression. However, the interactive
effect of self-oriented perfectionism and loneliness came close
to accepted significance levels, t (81) = -1.90, p = .061, suggesting
the association between loneliness and depressive symptoms might
depend on levels of self-oriented perfectionism. This finding is
also consistent with studies demonstrating self-oriented perfectionism
is maladaptive, and significantly associated with depressive symptoms
(Enns and Cox 1999; Flett et al. 1991; Hewitt and Flett 1991a).
Since loneliness has been correlated with measures related to self-oriented
perfectionism, such as self-blame, self-deprecation, and social
comparison, it might be expected this interaction would be close
to accepted significance levels.
Limitations
Several
limitations in this study may have produced unexpected correlation
and regression analysis results. Hewitt and Flett’s distinctions
between self-oriented, socially prescribed, and other-oriented perfectionism
can be difficult to decipher. It is unclear whether any or all of
these perfectionism dimensions are maladaptive or adaptive, though
past research suggests socially prescribed perfectionism is a maladaptive
trait, while self-oriented perfectionism is an adaptive one. However,
since these two dimensions of perfectionism are often positively
correlated with one another, it remains in question exactly how
accurately the MPS assesses individuals’ levels of perfectionism.
Repeating the current study with the FMPS may help alleviate some
problems defining the relationships between perfectionism, loneliness,
and depressive symptoms, because it presents clearer distinctions
between maladaptive and adaptive dimensions of perfectionism.
Another limitation regards the sample pool. The majority of participants
in this study were Caucasian, but research on perfectionism suggests
culture factors may have an effect on individuals’ levels
of perfectionism. For example, in a study conducted by Chang (1998),
Asian-American college students exhibited significantly higher scores
in maladaptive perfectionism, and significantly lower scores in
adaptive perfectionism than their European-American counterparts.
Literature regarding Asian Americans also indicates they are often
characterized as expressing excessive perfectionist behaviors in
comparison to Caucasian Americans (Yee 1992). Additionally, the
sample in this study was biased toward females and expanding the
study to a gender-equal sample would contribute to the validity
of the results.
The
subjects in this study were all recruited from an undergraduate
university psychology course. A college-oriented lifestyle may contribute
to perfectionist tendencies because of the stresses of both academics
and one’s social life. Additional studies should consider
measuring perfectionism in older and younger populations. Bandura
and Cervone (1986) suggest that perfectionist tendencies may be
the result of social learning in children, so the competitiveness
of one’s academic environment and perfectionism in an individual’s
family would strongly affect if and to what degree an individual
is perfectionist. Hence, at different age levels, individuals would
be subject to different pressures and exposure to imitative models
influencing levels of perfectionism.
Varying
perceptions of loneliness can affect tendencies toward negativistic
views on life, and affect one’s own self-image and degree
of self-criticism. Findings in this study indicate it is important
to extend and replicate results with alternative measures of perfectionism
(Frost et al. 1990) as well as examine relations between the present
variables in different racial and ethnic groups.
Conclusion
In
sum, the present study indicated that the three dimensions of perfectionism
measured by the MPS are highly correlated with one another. In addition,
the study found that the three dimensions of perfectionism are neither
unique main nor interactive predictors of depressive symptoms. Loneliness,
as measured by the UCLA Loneliness Scale, emerged as a significant
unique main predictor of depressive symptoms. This suggests future
research measuring depressive symptoms, and other negative affective
states should account for loneliness as a significant predictor
or potential interactive effect of these conditions.
The
present study also has implications regarding the importance of
conducting psychological research comparing the relative predictive
power of variables that are associated with similar outcomes. Loneliness
and perfectionism have previously been correlated with depressive
symptoms. By examining them together, it was possible to identify
if one was a more robust predictor of depressive symptoms than the
other. Integrating the different lines of research to test for interactive
results here provided new insights into the possible relationships
between these variables.
