Salary, Education, and Managerial-Level Differences of Physical Therapists in Maryland

Transcription

1 Salary, Education, and Managerial-Level Differences of Physical Therapists in Maryland The purpose of this study was to determine whether differences existed between a random sample of male and female physical therapists on selected factors. These factors included salary, managerial level, number of courses taken in management or administration, years of work experience in physical therapy, and years of seniority in an organization. A self-reported questionnaire was sent to 400 licensed physical therapists in Maryland who were also American Physical Therapy Association members. Data were analyzed on the 244 respondents using chi-square tests, t tests, and critical ratios. Results showed that female physical therapists, when employed full time in Maryland as department managers, on average, earned significantly less than their male counterparts. A significant difference existed between male and female department managers for full-time work experience in physical therapy. Neither the number of management courses taken nor seniority in an organization were significantly different for male and female physical therapists, regardless of managerial level Conclusions were that differences existed on several factors between male and female physical therapy department managers and that schools preparing physical therapists for entry into the profession should assess the need for management preparation.

The health care fields in general, and the physical therapy profession in particular, are predominantly female. In an era where women are entering traditionally male-dominated professions such as banking and industry, the question arises as to what is happening in the typically female-dominated careers such as those of the allied health professions. Of particular interest are differences in the representation of men and women in management positions and salary differences. In recent years, men have been assuming more leadership in the predominately female physical therapy profession. 1 A discrepancy appears to exist in the number of women becoming managers and their proportion in the total physical therapy work force. In 84, women comprised 77% of the physical therapy work force. 2 In a nationwide poll of physical therapists, Kemp et al found that 35.1% of their female respondents as opposed to 56.4% of their male respondents were chief physical therapists. 3 If it is assumed that all therapists receive the same basic physical therapy training, then women managers are not represented in numbers similar to their proportion in the physical therapy work force. Another area of discrepancy is in salary differences between male and female physical therapists. Since the late 60s, the median income of full-time female workers for all occupations remained at about 60% of men's income. 4 For the physical therapy profession, the US Bureau of the Census report for 80 listed female physical therapists earning, on average, $7,709 less than male physical therapists. 5 Kemp et al found that female chief physical therapists earned 25% less than did male chief physical therapists. 3 C Baker, MS, PT, was Chief Physical Therapist, Burch, Rhoads & Loomis, PA, 6305 York Rd, Baltimore, MD 21212, when this article was written.

This article was submitted November 30, 87; was with the authors for revision for 22 weeks; and was accepted August 15, 88. Given the previous findings of salary discrepancies and the relative representation by women in management, factors relating to the attainment of a managerial position may be important. The evolution toward management in physical therapy Physical Therapy/Volume 69, Number 1/January 89 27/41

2 begins with the basic physical therapy professional preparation, which in most cases has been a baccalaureate degree. To this basic preparation are added three factors: 1) continued education, 2) work experience in physical therapy, and 3) longevity of service with an organization. In this study, continued education refers to short-term courses in management or courses leading to a higher degree, especially in business or management. Work experience includes any practice as a physical therapist, whether at one or several organizations. Such experience could include some supervision of subordinates, such as physical therapist assistants or physical therapy aides. Seniority, in this study, means the length of time that a therapist has been employed in his or her present setting. Seniority may be especially important if promotions come from within the organization itself. Additional factors that may alter the managerial level of a physical therapist are individual motivation, job stress, part-time employment, or attrition. The purpose of this study was to examine physical therapists employed in Maryland to identify whether differences existed between men and women in management and staff positions. Managerial position was divided into categories of department manager (held a supervisory position), solo manager (owned and managed own practice), and staff (nonsupervisory physical therapists). Factors studied included whether the actual number of female physical therapy managers differed from the expected number of female managers in physical therapy; whether average annual salaries differed according to sex for managerial and staff levels; and whether male and female physical therapists differed on the factors of courses in management, work experience in the physical therapy profession, and seniority with an organization. Method Subjects The population studied were physical therapists who were licensed to practice in Maryland and also members of the American Physical Therapy Association. A random sample of 400 was chosen from the approximately 800 eligible physical therapists. Design Instrumentation. We designed a 29-item questionnaire based on items investigated by Kemp et al, 3 Guccione and Jette, 6 and the APTA membership profile of 82 as cited by Guccione and Jette. 6 Construct and face validity were examined by a panel of experts. We conducted a pilot study and determined reliability of the instrument using the test-retest method. After revision, the final reliability value for the instrument using the Pearson product-moment correlation coefficient was.85. Procedure. Data were collected during the early winter of 86. A mailed questionnaire and cover letter were sent to 400 physical therapists licensed by the state of Maryland who were also APTA members. The questionnaires included items on salary, managerial position, course work in management, and work experience in physical therapy. They were coded for anonymity and color-coded for sex. Except for report of salaries, nonresponses were coded as missing values. Salary responses were averaged for sex and managerial level. For those not responding to the question on annual gross income, average salaryfigureswere used. Confidentiality was ensured in the cover letter. Questionnaires were returned from 244 persons (61%). Because this return rate was considered excellent for mailed questionnaires and was sufficient for adequate data analysis, 7 we did not conduct a follow-up on nonrespondents. Data analysis. To examine managerial levels, we tabulated the actual, rather than proportional, responses for solo managers, department managers, and staff-level physical therapists for the total sample, as well as by sex, using the chi-square test for goodness offit.differences in average annual salaries of male and female physical therapists at managerial and staff levels were analyzed using a series of t tests for independent samples. Multiple Mann-Whitney U tests were performed for courses taken in management, sex, and managerial level. No differentiation was made between seminars, college-level courses, or management courses required for a business degree. The number of courses taken was divided into several categories. Zero to 3 courses indicated a casual interest in business or management. Four to 6 courses indicated a more-than-casual interest in business or management. Seven to 10 courses indicated a possible minor in business or management, especially if taken at the college level. Finally, more than 10 courses indicated a possible business major. We used a critical ratio or z test to investigate the differences between male and female physical therapists on number of years of physical therapy experience and years of seniority in an organization. For all hypotheses tested, a significance level of.05 was used. Results Of the 400 subjects sampled, 244 (61%) responded to the mailed questionnaire. The study population was composed of men (21.3%) and 2 women (78.7%). The mean age was 34.9 years, with men averaging 44.9 years and women averaging 35.2 years. All geographical areas of Maryland were represented by the returned questionnaires. The participants represented 57 schools of physical therapy, with 38.5% attending the University of Maryland. The entry level into the physical therapy profession was 82% by bachelor's degree; 78% reported that was the highest degree obtained. The average number of full-time years of experience in physical therapy was 8.5 (s = 7.6). The respondents included more staff physical therapists than managers. Of the 2 female respondents, 44.8% were in a managerial position and 55.2% were staff therapists. In 42/28 Physical Therapy/Volume 69, Number 1/January 89

Using the chi-square test for goodness offit,we found a significant difference (p <.03) at the.05 alpha level in managerial-level representation by each sex. A chi-square value of 7.11 indicated a significant difference in the observed frequencies of men and women in each managerial level versus the expected frequencies (Tab. 2). Because of the extreme variability of part-time employment, we decided not to use part-time physical therapists for data analysis and conclusions. Using only full-time employment, no significant difference was found between the observed and expected frequencies of women in managerial positions in Maryland (x 2 [1, n = 2] = 3.48, p>.05, α =.05).

Using the t test, we found that, at the.05 alpha level, a significant difference existed between male and female physical therapists in average annual salaries for the total sample (p <.001). Among those physical therapists who worked full time, significant salary differences existed, at the.05 alpha level, between the sexes for all managerial levels (p <.001), for department managers only (p <.001), and for solo and department managers combined (p <.02). No significant salary differences existed between the sexes of those respondents employed in full-time solo management (p >.05) or full-time staff-level positions (p >.05). From this analysis, we found the following significant salary differences (p <.05) between male and female respondents: 1) Women employed full time earned 21% less than men employed full time, Multiple Mann-Whitney U tests revealed no significant difference existed at the.05 alpha level between male and female physical therapists on the number of courses taken in management, regardless of managerial level. Our examination of part-time and full-time years of work revealed no significant difference (p >.05) between male and female physical therapists practicing in Maryland on the number of years of full-time work experience (z =., α =.05). When examining part-time years for the same group, we found a statistically significant difference (z = 7.09, a =.001), indicating that women have a significantly higher number of years invested in part-time physical therapy employment (p >.05). Because we chose to specifically investigate full-time employment, only those respondents employed full time were included in further evaluation between male and female physical therapists. No significant differences were found between male and female physical therapists practicing in Maryland on the factor of full-time work experience except at the managerial level (z = 2.00, α =.05).

Manager Total By using critical ratios, no significant differences were found to exist between men and women for years of seniority in an organization (p >.05). Thisfindingwas true of all levels of management. The mean number of years of seniority was greatest for full-time male department managers and lowest for full-time male staff therapists. For managerial level, the mean years of seniority were greatest for full-time males ( = 6.33) and full-time department managers ( =6.06). Discussion and Conclusions According to APTA membership reports, as cited by Guccione and Physical Therapy/Volume 69, Number 1/January 89 29/43

4 Jette, 6 72% of the physical therapy profession was female. This study showed that Maryland is similar in its representation with 78.7% of the physical therapists responding being female. Based on the results of this study, we concluded that factors other than courses in management and years of seniority in an organization are reasons for attainment of a management position in physical therapy. Total years of physical therapy experience was significantly different between the sexes in only one managerial level, that of department manager. Perhaps factors leading to promotion to the management position should be examined more closely. The findings from this research reinforce previous studies of physical therapists on managerial levels. Moore et al identified that men were assuming more of the leadership positions than women. 1 Kemp et al found that 35.1% of their female respondents and 56.4% of their male respondents were chief physical therapists. 3 Similar results were found for this study. We found that 44.8% of the female respondents and 63.5% of the male respondents were in management positions, either in an institution or in solo practice. Among full-time practitioners, 47.5% of the women and 62.7% of the men were in management positions. This study also concurred with previous studies on average annual salaries. 2-3,8-10 In this study, women earned an average of 67.5% of men's salaries for all managerial levels, regardless of whether their employment was full time or part time. The significant difference found between male and female department managers' average salaries could have many causes. It may be the result of upper-level management's views of women in management. Women may be considered to have potential short-term employment because of marriage or pregnancy interruptions. Another reason for the difference in salaries may be that women lack the negotiation skills to demand salaries comparable to those of men. These salary discrepancies and reasons for them warrant further investigation. Berger suggests a third reason for salary inequity: sexual prejudice in job evaluation. 4 She stated that male names were chosen 10% more often than female names infillingteaching vacancies, even though men and women had similar qualifications. With the growth of group practices, it would be interesting to study how many male and female managers are employed in practices owned by each sex. The other factors studied courses taken in management, work experience in physical therapy, and seniority in an organization cannot be directly related to other research findings. Although studies have been conducted and suppositions made in the area of physical therapy management, no concrete indicators have been identified for promotion to leadership positions. 1,3,11,12 We did not address motivating factors in this research. Possibly not every physical therapist wants to be a manager. A written comment on one questionnaire in this study stated exactly that. Yet Kemp et al felt that men, in attempting to legitimize their career in a female-dominated profession, pursued promotions to management roles. 3 This need for autonomy may account for the fact that 23.5% of men in full-time practice were also in solo management positions, whereas only 8.5% of the women occupied the same position. In the area of work experience, we agreed with Conine who identified pregnancy and marriage as reasons for career interruption. 13 Our research showed that childbearing or childrearing was the primary reason given for career interruption. Three male physical therapists' careers were interrupted, one for education and two for other reasons such as travel. Of the 90 female physical therapists' careers that were interrupted, 71 were for childbearing or childrearing. Such interruptions could influence anniversary dates for annual and merit raises. We did not find a significant difference between sexes on seniority in an organization. This finding agrees with Harkson et al who noted mobility as a Table 3.

5 cause for lack of seniority in a physical therapy organization. 14 Another reason may be that women enter and exit the work force for childbearing or childrearing. Also men and women may change employment for career advancement, especially if they are employed in a large facility where internal promotions are slow. More investigation is needed to answer the question of why differences exist between the sexes and to look at possible changing trends in physical therapy practice. The physical therapy profession has not listened to Moore, who felt that physical therapy management development programs were inadequate. 12 The short-term courses offered to physical therapists continue to be geared predominately toward improving clinical skills. This is not necessarily a bad offering. Typically, however, a skilled therapist, one who has taken clinical skill-improvement courses, will be identified as a leader, promoted to management, and then, because of the management position, be unable to use these same clinical skills. Professional associations should expand management course offerings to the general membership and focus on basic management principles rather than specific managerial skills. Course offerings in the physical therapy curriculum should emphasize management education in the undergraduate and graduate levels to better prepare the future practitioners for leadership roles. In reviewing the curricula of eight physical therapy education programs, no school was found to offer more than two courses in management. Advancement to management could be considered to be a logical progression of a physical therapist's career. A basic preparation in management, therefore, should be included in the physical therapy curriculum to prepare each student for this future role. A careful examination of the present physical therapy curricula is needed to adequately assess whether the profession is preparing its members for management roles by offering them business or management courses within the basic curriculum. The proposal of the entry-level master's degree physical therapy program, that has been mandated for implementation by 90 by the APTA, would be the logical place for the inclusion of management courses as an upgrading of the basic professional requirements.
