                    Descriptive Analyses

 

    Wave 2 Demographic Characteristics

       After taking into account the attrition experienced by Wave 2 data,
     the final sample of respondents who were married, cohabiting or
     remarried was found to consist of 369 males and 368 females (n=737).
     The demographic characteristics of this subsample drawn from the
     WHADS dataset are outlined below.  Table 10 provides a complete
     summary of Wave 2 male and female demographic data.
 

     Age.

     The mean age for male and female respondents was 47.08 years (SD. =
     11.76, range 22-67) and 44.10 years (SD. = 12.03, range 21-68),
     respectively.  Frequency data for Wave 2 indicate a shift in the
     proportion of female respondents found in each age group.  For
     example, the proportion of respondents found in the 18- 34 year age
     group increased (33.4%) whereas the proportion of respondents found
     in the 50+ age group decreased (29.1%).
 

     Marital status.

     Wave 2 data included an additional response category for this
     variable (cohabiters).  The distribution of Wave 2 respondents was
     found to be predominantly married (90.5% of males and 91.6% of
     females) followed by males and females who cohabited with a partner
     (7.3% and 6.3%, respectively).  Only 2.2 percent of males and females
     were found to be remarried.
 

     Educational status.

     Wave 2 analyses conducted on six levels of educational attainment
     indicated that 56.9 percent of males and 51.1 percent of females
     achieved educational status beyond receipt of a high school diploma.
     Wave 1 data indicated a similar distribution pattern for males
     (53.5%) and females (49.6%).
 

     Current employment status.

     Results of Wave 2 data on current employment status are consistent
     with those found in Wave 1 for male respondents who were employed
     (84.4% in Wave 1 v. 79.4% in Wave 2) but not for females who were
     employed (62% in Wave 1 v. 40.2% in Wave 2).  The category that
     experienced a fivefold increase during Wave 2 is that of "student"
     for male respondents (.4% v. 2.2%).
 

     Income.

     Total family income was distributed across five broadly based
     categories. Wave 2 results indicated that among male respondents,
     56.2 percent reported a combined family income greater than $50,000
     per year.  The same category was represented by only 42.2 percent of
     female respondents.  Compared to Wave 1 data, both males and females
     report higher total family incomes in Wave 2.  For example, Wave 2
     reports of those earning combined family incomes of $50,000 or more
     annually increased from 43.8 percent in Wave 1 to 56.2 percent in
     Wave 2 for males and from 35.6 percent in Wave 1 to 42.2 percent in
     Wave 2 for females.
 

     Religious preference.

     The distribution of religious preference categories for both male and
     female respondents remained virtually unchanged from those reported
     in Wave 1 of this project.  The largest religious preference category
     indicated by respondents was Protestant (44.0% of males and 44.3% of
     females), followed by Catholic (25.8% for males and 31.0% of
     females).  Combined, these represented 69.8 percent (males) and 75.3
     percent (females) of all response categories.
 

     Race.

     As described above, the distribution of Wave 1 and Wave 2 data with
     respect to racial groups remained unchanged for both males and
     females. Descriptive analyses conducted on Wave 2 data indicated that
     95.7 percent of males (v. 93.3% reported in Wave 1) and 94.0 percent
     of females (v. 92.3% in Wave 1) reported being white.

     Rates of Perpetrated Partner Abuse

    Prevalence of perpetrated partner abuse.

     Descriptive analyses conducted on the entire sample of Wave 2
     married, cohabiting and remarried respondents indicated that 17.3
     percent of males (n=64, Range 6-22, SD. 1.50) and 27.4 percent of
     females (n=100, Range 6-17, SD. 1.47) reported perpetrating at least
     one episode of partner abuse at some point during their relationship
     with a current partner (p < .001).  The most common form of partner
     abuse tactic reported for both males and females was throwing or
     smashing something (but not at partner) (11.1% and 14.2%,
     respectively).  Table 11 summarizes an item analysis of the CTS for
     the prevalence of perpetrated partner abuse by males and females in
     Wave 2.

               by married, cohabiting and remarried males and females.

     Note: * p < .05, ** p < .01, *** p < .001
        For males:   overall scale means = 6.43, SD. = 1.50,
                   range = 6-22
        For females: overall scale means = 6.66, SD. = 1.47,
                   range = 6-17

       The following are the abuse tactics found to differ significantly
     by gender: 1) threatened to throw something (chi-square = 11.64, p <
     .05) , 2) threw something at partner (chi-square = 8.58, p < .01),
     3), and hit partner (chi-square = 10.60, p < .01).  In each case, a
     greater proportion of females was found to engage in the perpetration
     of partner abuse tactics.
 

     Comparison of Wave 1 and Wave 2 prevalence rates of perpetrated  
     partner abuse.

     To facilitate an objective comparison of Wave 1 and
     Wave 2 prevalence rates for perpetrated partner abuse, frequency
     analyses were repeated on both waves of data based on the same
     sample.  These analyses provided similar results to those just
     reported, and indicated that 17.5 percent of males and 27.6 percent
     of females perpetrated at least one episode of partner abuse during
     the course of their relationship with a current partner.  Compared to
     the prevalence rates of perpetrated partner abuse reported during
     Wave 1, Wave 2 data experienced a 35.01 percent reduction in abuse
     reporting by males and a 29.01 percent reduction in abuse reporting
     by females.

       Post hoc analyses found that 18.4 percent of the males (n=52) and
     25 percent of the females (n=63) who reported "abuse" in Wave 1,
     reported "no abuse" in Wave 2.  Furthermore, in order to test the
     possibility that respondents' denial of partner abuse may have been
     in response to social pressure,  correlations were conducted on Wave
     2 CTS and the EPQL scores.  Results indicated a significant negative
     correlation for female respondents (r=-.12, p < .05) whereby
     individuals who scored high on the EPQL (indicating a tendency for
     dissimulation) also scored low on the CTS.
 

     Recency of perpetrated partner abuse.

     In order to examine the recency of perpetrated partner abuse,
     married, cohabiting and remarried respondents were asked to indicate
     the last time they perpetrated any of the six partner abuse items
     against their current partner.  On average, the last episode of
     perpetrated abuse occurred 5.99 years ago for males (range 1-30, SD.
     8.10) and 7.33 years ago for females (range 1-36, SD. 8.22).  Of
     those reporting perpetrating partner abuse at some time, 56.5 percent
     of males and 35.7 percent of females indicated that their most recent
     episode of perpetrated partner abuse happened within the past two
     years.
 

     Incidence of perpetrated partner abuse.

     Frequency analyses indicated that 41.9 percent of males (n=26) and
     25.5 percent of females (n=24) who had previously reported
     perpetrating partner abuse also acknowledged perpetrating partner
     abuse during the past year.  This represents 7.1 percent and 6.6
     percent of all married, cohabiting and remarried males and females
     participating in this survey. On average, partner abusing males
     reported 3.08 incidents of abuse (range 1-11, SD. 2.85) during the
     past year, while partner abusing females reported 3.91 incidents of
     abuse (range 1-20, SD. 3.92) during that same time period.

       Chi-square analyses were conducted on individual partner abuse
     items as well as on the total partner abuse perpetrated during the
     past year.  Results indicated only one significant sex difference
     (i.e., males "threw or smashed something" more often than females).
     This item was also found to be the most common partner abuse tactic
     reported by males (5.7%).  "Pushing, shoving or grabbing" was found
     to be the most common partner abuse tactic among females (3.8%).
     Table 12 provides a summary of these analyses.

    Perpetrated Partner Abuse and Related Characteristics

     Demographic characteristics.

     In order to assess the bivariate relationships between current
     partner abuse (i.e., abuse occurring during the past year) and the
     demographic measures included in Wave 2 of this research, analysis of
     variance and chi-squares were performed on these variables.

       The mean number of partner abuse incidents perpetrated during the
     past year was found to be significantly greater for males who
     cohabited and who were unemployed, nonwhite and earned less than
     $20,000 per year.  Males who were 50 years old and over, reported
     significantly fewer partner abuse incidents during that same time.
     For females, the age group of 18 and 34 years was associated with
     significantly more partner abuse incidents perpetrated during the
     past year.

     Chi-square analyses indicated the following:  Significantly more
     males who had perpetrated partner abuse during the past year were
     found to be unemployed (50%), earned less than $20,000 per year
     (26.67%) , and belonged to the religious preference category "other"
     (17.65%).  Significantly fewer of these same males were also found to
     be 50 years and over (2.03%) and married (5.09%). Significantly more
     females who had perpetrated partner abuse during the past year were
     between the ages of 18 and 35 (11.4%), cohabited (27.3%), and had
     some high school education (14.1%).  Tables 13 and 14 summarize the
     results of these bivariate relationships for males and females,
     respectively.
