<strong>and</strong> their <strong>in</strong>teraction) by compar<strong>in</strong>g the goodness of fit of the<br />

model that <strong>in</strong>cluded the term to the goodness of fit of the model<br />

without the term. A backward elim<strong>in</strong>ation procedure was used<br />

to arrive at a parsimonious model that fit the data. For cases <strong>in</strong><br />

which significant effects were found, we exam<strong>in</strong>ed adjusted<br />

residuals to assess the effects of membership <strong>in</strong> particular categories<br />

of the <strong>in</strong>dependent variables (i.e., low- vs. average- vs.<br />

high-acceptance). We ran separate analyses for the two dist<strong>in</strong>ct<br />

operationalizations of friendship to learn how estimates of the<br />

prevalence of friendship, particularly among low-accepted children,<br />

are affected by changes <strong>in</strong> the str<strong>in</strong>gency of the criterion.<br />

The first logit analysis, us<strong>in</strong>g the looser, best friendship criterion<br />

found a significant effect for children's level of acceptance,<br />

likelihood ratio x 2 (2, N= 881) = 103.64, p< .001. Membership<br />

<strong>in</strong> the low-accepted group significantly depressed the odds of<br />

hav<strong>in</strong>g a friend, whereas membership <strong>in</strong> the high-accepted<br />

group significantly augmented these odds. Specifically, 45.3%<br />

of low-accepted, 82.3% of average-accepted, <strong>and</strong> 93.8% of highaccepted<br />

children had at least one friend. A ma<strong>in</strong> effect of<br />

gender was found, likelihood ratio x 2 (L N = 881) = 7.09, p <<br />

.01: Girls (81.6%) were more likely than boys (74.2%) to have a<br />

friend. The <strong>in</strong>teraction of gender <strong>and</strong> level of acceptance did<br />

not significantly alter the odds of hav<strong>in</strong>g versus not hav<strong>in</strong>g a<br />

friend.<br />

The second logit analysis, us<strong>in</strong>g the str<strong>in</strong>gent, very best<br />

friendship criterion, revealed a highly significant effect for children's<br />

level of acceptance, likelihood ratio x 2 (2, N = 881) =<br />

53.10, p < .001, <strong>and</strong> a nearly significant Gender X Level of<br />

Acceptance <strong>in</strong>teraction, likelihood ratio x 2 (2, N= 881) = 5.26,<br />

p < .07. Membership <strong>in</strong> the low-accepted group significantly<br />

depressed the odds of hav<strong>in</strong>g a very best friend, whereas membership<br />

<strong>in</strong> the high-accepted group significantly augmented<br />

these odds. Whereas 58.27o of average-accepted children <strong>and</strong><br />

69.5% of high-accepted children had very best friends, only<br />

29.3% of low-accepted children had very best friends. Furthermore,<br />

whereas the proportion of boys with very best friends<br />

<strong>and</strong> the proportion of girls with very best friends were roughly<br />

equivalent <strong>in</strong> both the high- <strong>and</strong> average-accepted groups<br />

(72.3% vs. 66.7% <strong>and</strong> 56.2% vs. 60.7%, respectively), low-accepted<br />

girls (39.5%) were twice as likely as low-accepted boys<br />

(18.9%) to have a mutual very best friend. A comparison of<br />

these results with the correspond<strong>in</strong>g results from the earlier<br />

analyses suggests that tighten<strong>in</strong>g the friendship criterion is particularly<br />

likely to affect the estimate of the number of low-accepted<br />

boys with friends.<br />

Next, us<strong>in</strong>g the more <strong>in</strong>clusive def<strong>in</strong>ition, we exam<strong>in</strong>ed<br />

whether there were differences <strong>in</strong> the number of best friends<br />

children had as a function of gender <strong>and</strong> level of acceptance. A<br />

2 (gender) X 3 (level of acceptance) analysis of variance (AN-<br />

OVA) yielded a highly significant effect for level of acceptance,<br />

F(2,875) = 81.02, p < .0001; a ma<strong>in</strong> effect for gender, F(l ,875)<br />

= 10.39, p < .001; <strong>and</strong> no Gender X Level of Acceptance <strong>in</strong>teraction,<br />

F(2,875) = 0.79, ns. Post hoc (Tukey) comparisons <strong>in</strong>dicated<br />

that low-accepted children had significantly fewer friends<br />

(M = 0.65, SD = 0.82) than average-accepted children (M =<br />

1.50, SD = 0.98), who <strong>in</strong> turn had significantly fewer friendships<br />

than high-accepted children (M= 2.03, SD = 0.89). Girls<br />

(M = 1.54, SD = 1.01) had significantly more friends than boys<br />

(M= 1.35, SD= 1.02).<br />

F<strong>in</strong>ally, we studied the relationship between the acceptance<br />

levels of very best friends. To accomplish this, we identified all<br />

dyads that met our sociometric criteria for very best friendship<br />

(A r = 351). We then classified each dyad accord<strong>in</strong>g to the level of<br />

acceptance of the partners. Of the 351 friendships, there were 9<br />

dyads <strong>in</strong>volv<strong>in</strong>g 2 low-accepted children, 36 dyads <strong>in</strong>volv<strong>in</strong>g a<br />

low-accepted <strong>and</strong> an average-accepted child, 3 dyads <strong>in</strong>volv<strong>in</strong>g<br />

a low-accepted <strong>and</strong> a high-accepted child, 179 dyads <strong>in</strong>volv<strong>in</strong>g 2<br />

average-accepted children, 104 dyads <strong>in</strong>volv<strong>in</strong>g an average-accepted<br />

<strong>and</strong> a high-accepted child, <strong>and</strong> 20 dyads <strong>in</strong>volv<strong>in</strong>g 2<br />

high-accepted children. A one-sample chi-square test revealed<br />

that the observed distribution of configurations departed significantly<br />

from its expected distribution, x 2 (5, N= 351)= 79.23, p<br />

< .0001, given r<strong>and</strong>om pair<strong>in</strong>g <strong>and</strong> the relative frequency of<br />

children <strong>in</strong> the three acceptance groups. Inspection of the st<strong>and</strong>ardized<br />

residuals from this analysis <strong>in</strong>dicated that the pr<strong>in</strong>cipal<br />

reason for this disparity rests with the pattern of low-accepted<br />

children's <strong>in</strong>volvement <strong>in</strong> friendships. Whereas the number<br />

of low-low friendship dyads was consistent with<br />

expectations (9 observed vs. 10 expected), the number of dyads<br />

<strong>in</strong>volv<strong>in</strong>g a low-accepted child with either an average-accepted<br />

or a high-accepted partner was markedly less than the number<br />

expected through r<strong>and</strong>om pair<strong>in</strong>g (36 observed vs. 82 expected<br />

<strong>and</strong> 3 observed vs. 17 expected, respectively). Thus, low-accepted<br />

children's relative lack of <strong>in</strong>volvement <strong>in</strong> friendships can<br />

be understood as a tendency for lower participation <strong>in</strong> friendships<br />

with better-accepted children, specifically, <strong>and</strong> not as an<br />

<strong>in</strong>discrim<strong>in</strong>ant tendency toward less <strong>in</strong>volvement <strong>in</strong> friendship.<br />

At the same time, it is important to note that low-accepted<br />

children's <strong>in</strong>volvement <strong>in</strong> friendship is not restricted to <strong>in</strong>volvement<br />

<strong>in</strong> dyads with other low-accepted partners. Indeed, the<br />

majority of dyads <strong>in</strong>volv<strong>in</strong>g low-accepted children were dyads<br />

<strong>in</strong>volv<strong>in</strong>g a low-accepted child <strong>and</strong> an average-accepted partner<br />

(36 out of 48 dyads, or 75%).<br />

<strong>Friendship</strong> <strong>Quality</strong><br />

Identification of subscales. To identify subscales on the<br />

FQQ, we performed a pr<strong>in</strong>cipal-components analysis (oblique<br />

rotation) on the responses of the 484 children with very best<br />

friends to the 40 primary items <strong>in</strong> the FQQ. This analysis resulted<br />

<strong>in</strong> six factors with eigenvalues greater than 1. The six<br />

factors, which were <strong>in</strong> close agreement with the predicted underly<strong>in</strong>g<br />

structure of the measure based on pilot test<strong>in</strong>g, were<br />

labeled Intimate Exchange, Conflict Resolution, Companionship<br />

<strong>and</strong> Recreation, Help <strong>and</strong> Guidance, Validation <strong>and</strong> Car<strong>in</strong>g,<br />

<strong>and</strong> Conflict <strong>and</strong> Betrayal. The rightmost column of Table<br />

1 shows the structure coefficient from the pr<strong>in</strong>cipal-components<br />

analysis for each item <strong>in</strong> relation to the factor on which it<br />

showed the highest load<strong>in</strong>g.<br />

The pr<strong>in</strong>cipal-components analysis was used to guide the<br />

cluster<strong>in</strong>g of items <strong>in</strong>to subscales. Specifically, we formed one<br />

subscale for each factor <strong>in</strong> the pr<strong>in</strong>cipal-components analysis<br />

by comb<strong>in</strong><strong>in</strong>g the items that loaded highly on each factor. Table<br />

1 displays the Cronbach alpha for these six subscales. As is<br />

evident, the <strong>in</strong>ternal consistency of each subscale was satisfactory.<br />

A child's score for each subscale was the average of his or<br />

her rat<strong>in</strong>gs for the relevant items (unit weight<strong>in</strong>g), after appropriate<br />

reverse scor<strong>in</strong>g if necessary. The six subscales were mod-
